The Shadow of the Gray House

Nine days. One ghost. And a guidebook that can destroy the whole world. Klim is sixteen, the school year is over, and summer vacation full of adventures is ahead, but his best friend Ern has drowned... And then returned as a ghost and unexpectedly asked to find his killer! Sirens, ghouls, harpies… What was once just a legend is now hunting in dark alleys. And somewhere nearby is the true master of the guidebook, ready to do anything to get back his collection. Klim couldn't handle it alone, so friends come to help, and together they try to save Ern's soul, and along the way, the whole world. A story about friendship, betrayal, and the monsters that are closer than they seem.
