Deathloop by G Bradley

I do not know why i persevered really, i didn't like the characters and the story line was predictable. Not a good book in reality.

When successful, charismatic lawyer, Zack Fortune, reluctantly agrees to take part in past life regression, the visions that confront him during the hypnosis are so horrific he cuts the session short. But the following day, a young woman, completely unknown to Zack, standing on a high roof calls out to him by name asking him to catch her, moments before she jumps and kills herself. When a strange boy starts to stalk him, and an ex-girlfriend accuses him of assault, suddenly Zack’s perfect world starts descending into chaos, and when, one by one, he comes across more strangers who call out to him to save them, moments before they die in tragic circumstances, Zack embarks on a desperate journey of survival besieged by demons that are determined to destroy him and drag him back to hell.
