Lovers and Other Strangers — Josh Lanyon

Recovering from a near fatal accident, artist Finn Barret returns to Seal Island in Maine to rest and recuperate. But Seal Island is haunted with memories, some sweet, some sad; three years ago Finn found his lover in the arms of Fitch, Finn's twin brother. Since that day, Finn has seen neither Conlan nor Fitch. In fact, no one has seen Fitch.

What happened to him? Did Fitch run away, as everyone believes? Or did he meet a more sinister fate? To put the past to rest - and see if there's any chance of a future with Con - Finn must discover the truth. But the deeper he digs, the more reason he has to fear Con is the only one who knows what truly happened to Fitch...
