Henkann. The Last Experiment

The terrifying events on the island of Sintar are behind, and life has already prepared a new surprise for Sorate. A woman from his past appears at the doorstep and begs him to find her kidnapped son. Henry suspects that things are not as obvious as they seem and that someone is waiting for them in a hotel abandoned many years ago — but not just them. The intertwining of empty corridors, like the intertwining of the fates of four strangers, harbors danger, old enemies weave their web, and inner demons break free.
To survive, Sorate needs Henry, but the secrets between them are becoming too many.
