Madison's Quest (Crime Tells #6)
Jory Strong

In and out of foster care as a kid, the best day of Tyler’s life was ending up in a group home where going to school meant meeting the Maguires and Montgomerys. He’s wanted Shane for years, but fear of losing what matters the most has kept him from acting.
They’ve never even dated the same woman. But when Madison comes to California and they’re assigned to her case, be it fate or Grandma Maguire’s matchmaking, desire threatens to land them both in Madison’s bed at the same time—and strip away years of denial.
They want her. Madison wants them. But how can she have the happy-ever-after she longs for when claiming a future with Shane and Tyler will mean breaking a promise she made in the past?
