Jailhouse Glock — Lizbeth Lipperman

As a war widow and a single mother, rookie cop Maddy Castillo isn't exactly flush with cash. But her money problems are nothing compared to the trouble that starts when she's framed for murder.

Lucky for Maddy, her three sisters and the ghost of her fourth sister are on the scene to help. And help is exactly what Maddy needs -- hardened criminals have descended on Vineyard, and Maddy's all tangled up in their hunt for a prized possession worth millions.
