The long, bright days of Midsummer hide dark and deadly secrets in this gripping Scandinavian crime thriller.    In 1994, thirteen-year-old Fredrik Fröding lost his entire family in Europe's worst ferry disaster, the shipwreck of MS Estonia. Twenty-five years later, still suffering from PTSD, he remains convinced that his younger brother survived. And when Fredrik thinks he sees him in a Stockholm hotel, his obsession drives him to follow the hotel's owner to Ulvön Island to find out the truth.

Flowing from the past, a current of deception and lies raises the present body count--and threatens to drag both Sofia and Fredrik under  . . .
