Riley, Sammy, Mia and Scarlett are art students at Monroe and working on projects together when one day, Sammy suggests a trip to Whisper Island, Alaska, where they could spend their holidays for free and profit from its remoteness and special surroundings for their artwork. Even though the others are not too keen on spending summer in the cold north, they agree and see it as an adventure. When they are on their way, Sammy announces that her brother Rob would join them, not just does she thus destroy the girls trip, but especially Mia is angry, her best friend should know that after their breakup, the wounds that Rob had caused never really healed. When they finally arrive, it is not just Rob but also his new girlfriend Opal awaiting them in a run-down house. But not only their lodging is a disappointment, also their boat to travel to the next town is out of order and then their whole trip turns into a nightmare when they realise that they are obviously not alone on the island since a murderer is on the loose killing one after the other.

Carissa Ann Lynch has chosen a classic locked-room setting which strongly reminded me of Agatha Christie’s “And Then There Were None”. Even though the students are not total strangers, they evidently know much less from each other than they thought before their departure. The story is narrated alternatingly from the points of view of the characters thus providing insight in their hidden thoughts and offering the reader, on the hand, clues to what could be behind all this murdering but, on the other hand, also a lot of red herrings which keeps suspense high.

The present events on the island are surely the main focus of the plot, however, the girls’ past, the things they hide from the others – and astonishingly, each of them has quite a story to offer – are much more interesting to unravel. Sammy soon hints at the fact that she did not suggest the trip out of the blue but actually had a good reason to vanish from Memphis and so had her brother. Mia seems to have been in a scandal a couple of years ago which she hopes the others have never heard of but of which the anniversary is close and threatening to make the others a see side of her she prefers to keep hidden. Scarlett struggles with drug abuse and hopes to get sober in the weeks on the island. Riley is new to the group and she is also the one who is quite closed up not giving away too much form herself and her family, so, what does she have to hide?

I liked the atmosphere on the hardly welcoming island which immediately gives you the creeps and fits perfectly to the plot. Speculating about why the six might have been chosen as targets was great fun and finally was revealed and explained. An entertaining and fast-paced mystery following a classic structure. ( )
