Lost In You by T.T. Kove

I met him by chance—and everything changed.

Pain and grief are a constant part of Matt’s life nowadays, all made worse by his depression. When he’s forced out of bed to go to a party with his sister, he meets Caesar—and everything changes.
Caesar is flamboyant, social, and generally fun to be around. Caesar shows Matt what he’s been missing, both in and out of bed, and for the first time in years Matt feels alive again.

But Matt fancies someone else, and Caesar’s keeping secrets that could potentially have life-threatening consequences. Will these two lost souls get their shit together?
