On the Edge by Lynn Hagen

Joe loves his new neighbors. Ben and Jericho are the sweetest men. Too bad their friend is a straight-up prick. Milo is also the sexiest man Joe has ever laid his eyes on. When they have an argument, sparks fly between them, and Joe can’t seem to stay away from the gorgeous man, even though Milo rubs him the wrong way.

Milo has always lived a carefree life. When he suddenly gets custody of his niece, his world flips upside down. Instead of hot men in his bed and living life on his terms, he’s knee-deep in diapers and teething. He doesn’t think Joe wants to be saddled with a mate and a baby, so he keeps the human at arm’s length. But his jaguar isn’t having any of that, and soon Joe becomes an essential part of Milo’s life. He thinks things are finally going smoothly, until Nicole’s shady father shows up demanding his daughter, and Milo has a fight on his hands.
