“Tahoe Ghost Boat” is the 12th and latest installment of the Owen McKenna mystery series.

Lake Tahoe author Todd Borg is releasing the book this summer.

It is about a 15-year-old girl named Gertie O’Leary. She has a messy bird’s nest of red hair, a serious softball pitch, and a dream to be a movie director. She also has a $2 million price on her head.

When Gertie is kidnapped as part of an extortion plot, Tahoe Detective Owen McKenna gets involved. But McKenna finds himself up against his toughest opponent yet, a killer the FBI calls Mikhailo The Monster.
