The final book in the series takes off right at the end of volume five, and twins, Sophie and Josh Newman travel back in time to a fabled city of the past where they meet their real parents - so they're told - Isis and Osiris, but you should know by this point that nothing is what it seems in this series. It's a bit like an episode of Mission Impossible where people keep pulling their masks off to reveal that they're really someone else.
Sophie heads off to destroy the ancient city which is required in order for civilization to flourish, and Josh sits on a pyramid, which sounds painful - but which might explain his pissy attitude - and discovers that Clarent and Excalibur are actually part of a quartet, which includes Durendal and Joyeuse. Who knew? There are lots of battles, double-crosses, feints and reveals, and so much talk of silver and gold that I expected Burl Ives to show up singing his Christmas song, but he doesn't.
Overall I consider this entire series to be a worthy read.
