Handle With Care by Cari Z.

A fragile heart needs extra care.

Burned-out social worker Aaron McCoy is on vacation for the first time in years–boss’s orders. Road-tripping to his brother’s wedding with his best friend, Tyler, seems a fun way to spend the mandatory two-week leave, and they set out for Kansas–and a difficult homecoming.
Aaron’s mother was a drug addict, and his adorable younger brother was quickly adopted, while Aaron spent his childhood in foster care. As Aaron mends fences, Tyler hopes to show him that this time, he won’t be left behind to face his problems alone.
Aaron’s opening up to how right it feels to be with Tyler and to the possibility of taking the leap from friends to lovers. But along with the wedding celebration comes a painful reminder of the past. Aaron’s heart is still breakable. Can he put it in Tyler’s hands?
