I went through AO3 and loaded up my Kindle with a bunch of SGA stories over 15000 words. Here are some of my favorites.
Life After by sian1359 - life after Season 5
John/Rodney and a bunch of the others. Seriously, they will surprise you! I wish there had been MORE to this. It just sorted of ended and I was so very sad because I wanted to know more about their lives.
These Proverbs We Made in the Winter Must End by siria
Ronon/Jennifer & Rodney/Teyla/John. LOVED this story. I'm not a huge lover of Jennifer Keller but this story made me a Ronon/Jennifer believer and LOVER! It is set after canon and they explain away the horribleness of Season 5 when it comes to that pairing. The author intersperses some early Ronon life scenes that help bring the character even more to life. The storyline is also very interesting and very believable.
A Hole in the World by
gottaloveva big ol' dose of the good kind of John/Rodney
The quote at the beginning of the story tells you everything you need to know about what you're getting into with this story. Read it and then hang on because you won't be able to stop. I thought I knew where it was going but I didn't so I was forced to read and read and read like a mad man because my heart was breaking right along with John's. The ending was perfect and ever so lovely!
His Woman by CJ aka WritinginCT
Ronon/Samantha (crossover with SG1)
I CRIED while reading this! At first I was like,
seriously, Ronon and Sam? but I read it because it was Ronon and I'm bound and determined to read every Ronon story out there. What a perfect pairing!!! This story is told slowly and with glorious detail so that the reward at the end is just perfect enough that the tears leaked out of my eyes before I could stop them. The friends left behind bring some great angst to the story.
Know How to Fall by
auburnJohn/Rodney with a good dose of Ronon/Amelia that left me wishing for more
This was the first fic that I read on my Kindle and was the one that firmed up the decision to read more. A story set in a world (three-day event riding/equestrian) that I don't understand quite as much as I do other alternate SGA universes but is so well described that I didn't have any problem enjoying the story. In fact, I wanted to VISIT the farm and see it all for myself. This was also my first AU story and I loved how the characters were all IN CHARACTER yet in a different world.
Open Your Eyes by thedeadparrot
John/Rodney
Another AU set in a world not unlike
Friday Night Lights where John is a head football coach and Rodney the crusty science teacher. This story had these little flashes of brilliance. The play by play of the games was really well done and I believed it even if I didn't really know exactly what they were talking about. *grins* The storyline with Ford was superb!
This isn't the complete list of what I've read but the ones that have stuck in my head. If you have any recommendations of your favorites (I've been lazy and have only gone looking on AO3 because it's a one-step download instead of a couple of different steps), let me know and I'll add them to the list!
