...at least, according to my Amazon Kindle purchases/borrows list:
"Simon vs. the Homo Sapiens Agenda" by Becky Albertalli - Loved it. Read it in a day, then re-read it again the next day. I loved Simon. And the secondary characters were mostly so well drawn that I wanted new stories from their points of view. It was also very nice to have a gay main character who is pretty secure in himself, generally happy and with a happy family, and ends the book even happier. These are teenagers and they act like teens, for the most part, without seeming too grown up. They make stupid mistakes but always believable. Just really good.
"That Eighteenth Summer" by Raine O'Tierney - Pretty good. I wish we got a little more of Luca's point of view, though. I'm not really sure why he's attracted to Ollie at all.
"Faith & Fidelity (Faith, Love, and Devotion Book 1)" by Tere Michaels - Liked it, but from the gushing reviews that I've read, I expected more. I cried, but honestly, it didn't do anything too out of the standard.
"Two Boys Kissing" by David Levithan - So, apparently I need to stop with David Levithan books because I couldn't get through this one. Which is the second of his books like put me off almost immediately. I liked "Will Grayson, Will Grayson," which he co-wrote, but clearly I just don't like his stuff, generally.
"Widdershins: A Novel of Gay Paranormal Romance" by Jordan L. Hawk - Fun. Reminds me of the "The Charm of Magpies" series.
"How to Repair a Mechanical Heart" by J.C. Lillis - Very good. Clearly a writer who knows her shipping and fanfic.
"Out of the Blues" by Mercy Celeste - Liked it, although I wish that we'd been able to see more of the character depth earlier.
"Frat Boy and Toppy (Theta Alpha Gamma Book 1)" by Anne Tenino - Fun, nothing deep.
"A Royal Affair (Book 1 in The Royal Affair series)" by John Wiltshire - Interesting. I generally enjoyed it with some reservations. Maybe will read the sequels, although this story was pretty wrapped up.
