The Book of Doors by Gareth Brown (Bantam, £16.99)
When Cassie receives the gift of a small leatherbound book, her life is transformed. It has the power to make “any door every door”, allowing her to walk out of her New York apartment on to a street in Paris, Venice, Prague – anywhere she’s been, or seen a picture of. Her best friend, Izzy, worries about how criminals could use it, while Cassie thinks they should just enjoy this amazing freedom. But Izzy was right to worry: the Book of Doors is just one of a small number of magical books, each with a different power, and although not many know they exist, some collectors won’t stop at murder to get what they want. What begins like a joyous daydream soon becomes a suspenseful thriller. It’s a truly magical book: exciting, intricately plotted and emotionally compelling.
