Most well-known for his bestselling Bartimaeus Sequence of illusion novels, he also penned the Lockwood & Co. books and such specific fantasy game titles as Buried Fireplace and The Step. He was a sickly kid; because of this, he spent a big part of his young years reading and composing. He continued to study books at the College or university of York. In his early adulthood, he proved helpful in London as an associate from the Walker Books editing and enhancing staff. His relationship to children’s reserve illustrator Gina Stroud led to a boy (Arthur) along with a girl (Isabelle). He and Harry Potter writer J.K. Rowling both had written works of youthful adult illusion fiction.
