"Why?" - this burning question is on everyone’s lips. Why does a guy like Mateo Walsh want to die? At seventeen he is Britain's most promising diving champion. He is the object of adoration, an excellent student and lives in the richest area of London. He has great friends and is the envy of everyone around him. And most importantly, he is deeply in love with his girlfriend Lola. He was always a decisive, balanced guy...Until one day off. A day he apparently doesn't remember. He only knows that he returned a different person. The one who no longer knows how to have fun, who no longer wants to spend time with friends, who no longer enjoys diving. Something terrible happened that day - something cruel, bloodthirsty and confusing. He doesn't know who he is anymore. He no longer trusts himself around people - he only wants to hurt, wound and destroy. He slowly recovers buried, shattered memories and finds himself staring at the reflection of a monster. Suddenly, exhausted, Mateo is faced with the most devastating choice of his life. Keep your secret and expose your closest people to terrible danger. Or confess and lose Lola forever...
