Well, Richie Tankersley Cusick does it again with this spooky, romantic, and at times even actually scary, young adult novel. For those who enjoy Cusick's unique recipe of romance, mystery and horror, 'Trick or Treat' will not fail to tantalise the tastebuds, with classic trademark ingredients such as the irresistable yet doomed to be persecuted heroine, the two signature love-interests (one nice and wholesome, the other excuding mystery and danger, yet invariably attractive), enough suspects to form a football team, and, as always, a masterful, eyes glued to the page, edge of the seat ending that only Cusick, from all the Point Horror series writers, seems able to achieve. The relationship between Martha (the protagonist) and Conor (her new step-brother) is especially electric, if at times positively verging on the incestuous. Overall, I feel the mystery element works very well, and the reader is constantly unsure of who the perpetrator may be. One thing I love about Cusick's books is the fact that up until the very last second the reader is left in a state of uncertainty, with Cusick throwing red herrings at us left, right and centre. So, if you're looking for thrills, spills and chills (but not necessarily literary genius) treat yourself to this classic Cusick.
