Ollie Jolson knows there’s something wrong with his new street, but he can’t quite put his finger on what. Maybe it’s the way the internet keeps crashing, or perhaps it’s the space outside old Mrs Dibkin’s house that drains away all sound. And when Ollie wakes in the middle of the night to find a mysterious silver-suited ‘fixer’ on his doorstep, he definitely knows something is amiss.

When he confronts the intruder, Ollie is thrown into a parallel world: a mysterious castle populated by zombie-like slaves who blindly follow the orders of the evil Lord Wight. With the help of new friend Niff, can Ollie uncover the castle’s strange secrets and get back home?

As a fan of Sean Williams’s YA trilogy The Broken Land, I was excited to see what he had to offer younger readers, and Castle of the Zombies did not disappoint. It’s a thrilling, imaginative read, perfect for ages seven and up. Paired with comic-book-style illustrations from the brilliant Nial O’Connor, this first book in the Fixers series is sure to be a hit with younger readers who like their adventures with a bit of a fantastic bent.

Be sure to keep an eye out for the rest of the series – book two, Planet of the Cyborgs is out now, with Curse of the Vampire and Invasion of the Freaks soon to follow.
