Wow. Just finished this second book in the ‘Mortal Engines’ quartet and boy, was it fun. You do need to have read the first book to have some idea about the characters and parts of the plot but if you have, then you'll find ‘Predators Gold’ a very worthy second visit to the future world of Philip Reeve's imagination. Reeve's characters continue to grow and have an amazing depth which is brilliant in a supposed ‘kids’ book. Full of drama, humour, scares, death, love, hope and despair, ‘Predators gold’ ticks all the right boxes as a classic adventure story. Kid's, if you haven't read ‘Mortal Engines’ yet, then do yourself AND your parents a favour, buy the series. You'll enjoy it and so will they I'm sure.
