Shock [EPUB ebook] 

Gaia is heartbroken when her best friend and boyfriend Ed breaks up with her. He thinks she has been distant lately, but she doesn’t have time to dwell — she and Sam are off to uncover the secret behind Tom’s coma. While snooping around the Berkshires compound, they come across an old man who has ties to Loki. Will he be of help to them — or is he responsible for the various attacks on Gaia’s life? Or is Sam the one who’s after her?
