Dead in the Water — Annelise Ryan

Deputy coroner Mattie Winston is starting to feel like she's in way over her head . . .

As the single mom of an energetic toddler and an investigator working for the medical examiner's office in small-town Sorenson, Wisconsin, Mattie is used to her life being a juggling act. But now that she's moved in with Detective Steve Hurley and his teenaged daughter Emily, and has started planning their wedding, her home life is looking more like a three-ring circus. And with her boss and friend, Izzy, suddenly having a health crisis, she could not be more grateful for the newest staff member in the ME's office, Hal Dawson.

All too quickly her gratitude turns to shock when a floating body found trapped against a dam turns out to be Hal, but the cause of death isn't drowning -- his throat's been slashed. Hal was supposed to be fishing on his day off with his girlfriend. And when their empty boat is found in a nearby lake, the whereabouts of the woman becomes an even more urgent question.

To find out what really happened to her coworker, Mattie may need to rock the boat. But a killer is just as determined to keep the truth from ever surfacing, even if that means making Mattie the next one to go under.
