The Raw Shark Texts is one of the most imaginative and unique books I have read in a long time and I loved it. Eric unleashes a ludovician, a conceptual fish that eats memories which is why he doesn't remember. When he starts receiving letters from himself, he follows the clues and is a lead on a wild journey trying to piece together his memories and find his life, meanwhile never knowing quite who to trust and if he can even trust his former self. The story is one wild, creative ride and will test the depths of your imagination.
The Raw Shark Texts by Steven Hall
"Eric Sanderson wakes up in a house he doesn't recognize, unable to remember anything of his life. All he has left are his diary entries recalling Clio, a perfect love who died under mysterious circumstances and a house that may contain the secrets to Eric's prior life. But there may be more to this story, or it may be a different story altogether. With the help of allies found on the fringes of society, Eric embarks on an edge of your seat journey to uncover the truth about himself and to escape the predatory forces that threaten to consume him."
