Lunatic

Filled with pulse-pounding intrigue, this detective mystery will keep you guessing until the shocking end.
When Detective Danielle Foster returns to the 66th Precinct after a maternity leave gone wrong, the unforeseeable death of her infant son who died of SIDS isn't the only tragedy weighing heavily on her mind. The latest female victim, found naked and brutally bludgeoned to death in the middle of Brooklyn's largest park, stirs in her dark ruminations she can't shake.
Recently transferred from Vice as a means to appease his overbearing wife, Detective Carter Dobbs has a lot to prove at the Special Victims Unit, and his new partner, Danny hasn't exactly welcomed him with open arms. As they charge headlong into a puzzling and increasingly disturbing investigation that takes them from picturesque Prospect Park to the seedy underbelly of NYC's modeling world, these brilliant and tireless investigators will stop at nothing to crack the case, even if it means putting their own complicated lives on hold.
What seemed at first to be a horrific but impulsive crime proves to have wider implications and soon the full extent of the killer's demented work becomes clear. Suspending hostilities, Danny and Carter barrel ahead in hot pursuit of a cold-blooded killer who draws them deeper and deeper towards the wicked truth, one which will threaten to shatter everything the detectives thought they knew about justice.
In the city where crime never sleeps, Danny and Carter must battle their own personal demons as well as a killer more depraved than any they've hunted before. But will they survive the investigation when it begins to strike far too close to home?
