Ben & Gavin by J.H. Knight

For Ben Cartwright, having a twenty-one-year-old lover comes with a lot of responsibility and a lot of worry. Mostly he worries that Gavin is tying himself down without knowing what his options really are.
Gavin has his own baggage to deal with, including old wounds from a family who disowned him when he was only a teenager.
As they struggle to meet in the middle after a short but painful breakup, Gavin’s pregnant sister lands on their doorstep and spins their world off its axis. At the heart of the chaos, though, Ben and Gavin manage to fall in love all over again. This time for all the right reasons.
