Lessons in Chemistry by Colette Davison

What do a nerd, a jock, and a slacker have in common? Each other.
When Auggie’s controlling father threatens to cut short his studies, it’s time to put his life in order. Add one cute nerd and one dedicated swimmer, and he has a new lesson to learn—how to love.
Emory is all kinds of confused. He really, really likes Auggie but is also in love with his best friend, Casey. Then Auggie comes up with a plan to see if Emory and Casey share any chemistry, and nothing will ever be the same again.
Casey lives for swimming and snuggling his best friend, Emory. Except Emory is in love with him, Auggie’s confusing him, and suddenly he has to confront his feelings and his sexuality.
Three men and one conundrum. How can they all get the guy?
