Prince of Mist by Carlos Ruiz Zafón

By teen lib

“A mysterious house harbors an unimaginable secret.”  And that is the house that Max and his family have just moved into leaving the capital where they used to live and moving to a small coastal village to escape the war.  Just after moving in, Max meets Roland, a boy just a couple of years older than him, and they make plans to spend the summer diving off the coast in search of treasure from a shipwreck that occurred there several years ago.  But the Prince of Mist has been waiting in the shadows of this small village, biding his time and gathering his strength so that he can collect on an unpaid debt from the past—one affecting everyone Max cares for most.
