Point of Betrayal — Ann Roberts

Rebuilding is hard, especially when both hearth and heart have been badly wounded. Renovating her home after an explosion occupies most of Ari Adams' time. Her heart remains unhealed -- nine months later her former girlfriend, Molly Nelson, is still not speaking to her. Worse of all, that wound was self-inflicted.

Trying to move on, Ari turns to private investigator Biz Stone for solace. When her best friend Jane arrives with a disquieting story of a dead social worker and murky motives for murder in California, Ari naturally asks Biz to go with them. Molly, meanwhile, would do anything to prove that Biz is a lowlife who spiked Molly's police career, murdered a witness and most definitely stole her girlfriend.

Betrayals of more than one kind form the tightening net of danger that surrounds Ari in this fourth installment of Ann Roberts' critically acclaimed series.
