Nightsiders by Gary McMahon

This is the story of Rob and his family. They arrive at their new house after a holiday to find another family has moved in, claiming ownership. The local police sergeant claims it is all above board, but offers to look into it, suggesting they stay in a local hotel in the meantime. From thereon, things start to go horribly wrong for the family, and over the course of one night, the final showdown will reveal things in their true light....

This is quite a disturbing novella, but in a good way. It kept me page turning and glued to the story. Some scenes were quite horrific, and had me wincing, I think they will stay with me for quite a while! The premise is a tried and tested one, paying homage to stories of its kind that have gone before, but the author takes this to a new level of fear and horror. I totally recommend this as I enjoyed it immensely.
