  1. Eternus Discipulus

    AARG… I’m getting withdrawal symptoms, NEEDS MORE…
    sorry to hear about your broken foot Btw, must have been nasty. For both our sakes i hope you get better soon.

  2. I just wanted to tell you that I re-read the “What Might Have Been” series for the second time. It’s like crack! Only in a good way! (Is it possible to have a GOOD addiction?)

    I appreciate your hard work in creating such a lush universe. I look forward to the future installments.

  3. I love this series and I can’t wait to see you continue it! I thought there was a short future fic story you wrote with Sebastian and now I can’t seem to find it. Does such a story exist or am I crazy?

  4. Hey, so I found your site a couple months ago and have just kind of single mindedly been reading EVERYTHING…. Like several times and now I can’t really remember if I ever commented (sorry:(). You are amazing, seriously I think you have beaten out Beren as my favoritefic writer. I cannot gush enough seriously. I’ve probably read ttb and wmhb 3 times each at this point. So good.

    Question for anyone though, what chapter in WMHB do they declassify the stargate program? I feel like I remember that scene but didn’t come across it in my re read

    • There is no scene but it takes place in between Rodney’s presentation in Chicago and John’s interview for the Science Channel. The only “tell” the reader gets is that that Stargate Program is mentioned in John’s interview.

  5. I have been rereading all of your stories since EAD and I was wondering something. What Might Have Been is finished now since you have moved onto Ring of Fire; does this mean that you will be putting it out in ebook format sometime, or will you wait until the whole series is finished?

  6. I am rereading WMHB currently and realized that Quark is not listet in the Cast list. You really should correct that, when you have time. 😉

  7. Just finished re-reading this for probably the 86th time, and it’s still my absolute favorite fic ever in the history of fanfic. I even ended getting myself a Maine Coon because I loved your Quark so much.
    Erm…please don’t take that to mean I am some sort of weird creepy stalker type person. Because I’m not. Swearsies.

  8. Is there any chance we’re ever going to get more information about *how* the Stargate program was declassified? As a side story, maybe? I just think about Rodney and Sam comparing lists of people they need to gloat to. The world’s initial reaction to the information. What information they would have released first, or if they would have just dumped it all on the public at once and hope that the abundance of information would keep people too engrossed to bother them for a while. What was the final catalyst that pushed them to declassification, or was it just decided “now’s the time”?

    ….. I just love declassification stories, but with yours we get to see so much happening even after declassification that most other stories don’t go into and it sets my imagination on fire.

  9. I am doing what seems to have turned into my at least tri-yearly reread of everything, and noticed that the internal link to Part 2 of When You Say You Love Me seems to be broken.

    One can work around it by going up to the What Might Have Been tag and finding the post of Part 2, but if you have time, it’s wonderfully convenient to have the internal links.

    Still loving your work, and looking forward to the next update of whatever lands on the site next!

  10. I’ve finally made it to the What Might Have Been universe & as expected, I’m loving it. I just read the part where John & Rodney are on Larry King’s show & I have to admit that John’s proposal touched a serious emotional chord in me. As a guy, I won’t admit to actually misting up, lol, but I’ll admit to being happy I had Kleenex close by 😉 Your SGA stories & various universes are awesome & I’m loving them all. Thank you for sharing.

  11. I went to the site today to re read What Might Have Been but the section that has the links to all of the stories seems to be gone. Just wanted to tell you in case something broke on the site. Love your stories! * switches to Harry Potter*

  12. I’ve been reading fanfic for years, but I always find my way back to you! Love your work. It one of the most original adaptions of a show/ book / movie etc. I’ve had. The multiple pleaseure of reading. Ebook??? Also Lantean legacy sequel???
    Thx 4 writing such amazing stories.

  13. When i get back home today i’m going to start re reading this amazingly beautiful piece of fanfic

  14. I have realized that reading one of your pieces of wonderful writing before bed is the worst idea possible. I am so into the story that I CANT STOP and HAVE to move onto the next chapter!! Tell myself, save it for tomorrow, savor it..but naww why wait when I can enjoy it now 🙂
    THANK YOU THANKYOU for such fun wonderful and bamfness!!

  15. This series is actually how I found your website. I read “We’ve Taken Different Roads” many years ago on Wraithbait. When I got back into Stargate Atlantis fiction, I wanted to read it again, but could only remember one line: “You realize offering to take an astrophysicist into space and another planet is literally like offering to suck his dick?” So, thank you for coming up with such memorable lines so that I could find it again. 🙂

  16. I don’t know why I never read this series before. I have been stalking your site for years (I came for Tangled Destinies and then found your Harry Potter fics) and I’ve re-read some things over and over but for some reason skipped over your SGA stuff. That was so very wrong. Your John and Rodney are fantastic together. I love the way you right John so very much.

    This series was wonderful from start to finish. I love their relationship from their first date on Mars to the parenting discussions they have. The whole things was wonderful and made me smile like an idiot every time they said “I love you”. You are so talented and i am so pleased youndecide to share. Thanks very much!

  17. I have read this so much it’s like a well loved movie, I know most of it by heart. But also like a well loved movie, I still come back again and again.

  18. Time for a reread. I’ve got a nasty cough and I need some excellent writing to get me through it!
