Who's There? is a book that intrigued me immediately; it's quite a simple idea really, a drug dealer taking advantage of a disabled person, but Kerena Swan has created such multi-dimensional characters who carry the plot along at a rate of knots.

Arnold Eastwood is a brilliant character who I took straight to my heart. Disability aside, I loved how he was addicted to Clint Eastwood films and saw the world as a much kinder place than it actually is. It was lovely to look through his trusting eyes for just a second before reality struck and Arnold got trapped in drug dealer Poker's web. I was so angry at the way Arnold was taken advantage of; I felt like I wanted to reach into the book to rescue Arnold and give Poker a good hiding while I was there (and I'm not a violent person!).

Although it's quite a dark story in relation to drug use and drug gangs, there are a lot of heartwarming and hopeful moments. I can't forget shop owner Madge who took a chance on Arnold and gave him a job or Chip who tried to help Arnold escape Poker's clutches. I also found it quite eye-opening regarding Social Services; Arnold was forgotten about when his case worker went on holiday, but rather than feel angry about this I could see how much strain Social Services are under. It's easy to point the finger in that direction and they often get bad press but Kerena Swan humanises Social Services and reminds us that they're only human after all.

A thought-provoking and highly suspenseful thriller, Who's There? is one of those books that you could easily read in one sitting, if you have the time available. I was completely invested in Arnold's story and couldn't read fast enough to find out how it would all play out. Who's There? is a very scarily realistic thriller with a big heart.

I chose to read an ARC and this is my honest and unbiased opinion. ( )
