So here is a break down of some of my favorite books by primary troupe. Heads up, I don't really do science fiction or fantasy yet... almost all of my suggestions are considered Contemporary with a smattering of historical. If you're looking for Wizards, Werewolves, or Spaceships you're not going to find much here.
Boy Aquarium: Who doesn't love a good Hockey book?
Rachel Reid's The Shots You Take
Tal Bauer's The Fall: This is easily my favorite book out of everything I've read in the M/M genre.
Hurt/Comfort: The catch all of M/M
N.R. Walker's Galaxies and Oceans
Brair Prescott's Until Trilogy
Wren Wild's Stormy and Levi: The first and third books in the ongoing Florida Panhandle Series.
Injured MC: Is he dead?
N.R. Walker's Missing Pieces Trilogy
Wren Wild's Benji: the second book of the ongoing Florida Panhandle Series. Suggest reading Stormy first.
