“Ptolemy’s Gate– Trapped for years on earth, Bartimaeus’s energies are fast running out. His master, Nathaniel, is increasingly arrogant and unapproachable and will not listen to his pleas. But as war and unrest rock the magicians’ government, Kitty uncovers secrets from Bartimaeus’s past that might help change the world forever.”
This trilogy starts darkly but from there gathers speed and warmth. The series sniffs of British sarcasm, attitude and humor. I would highly praise it and suggest it to most.
