Hot Six by Janet Evanovich
First there's fellow bounty hunter Ranger, currently on the run from a murder rap and requesting Stephanie's help. Trouble is she can't decide if she should turn him in or keep him for herself. Then there's sexy vice cop Joe Morelli - the man her heart says she's in love with (even though her head says otherwise). He's after Ranger too - but for less romantic reasons. . . And now there's another male in her life. He's big, he's orange, and he howls when he's left alone. Sexual temptation, homicidal maniacs, car crashes and doughnut addiction are all part of Stephanie Pum's daily routine. But all that pales into insignificance when Grandma Mazur moves in . . .
