You''ll probably guess what''s behind the murders of mothers and their very young sons long before investigator Joe Lassiter does, but that shouldn''t spoil your enjoyment of this exciting and thoughtful new thriller that mixes science and faith with action. Lassiter''s own sister and beloved nephew are among the victims, who were all patients at an Italian fertility clinic run by a doctor with some unusual ideas about DNA. Why this catches the attention of a dangerous religious order, and whether Lassiter can save one surviving woman and child from their wrath, should take up a good part of your night.
