In this final volume of Percy Jackson's adventures, Kronos and the Titans make their attack on Olympus. With the gods tied up fighting battles elsewhere, it's up to the halfbloods to defend Manhattan.
This book had some great moments - but on the whole, I wasn't as impressed as I was with the previous four. Maybe I just have trouble when a good series comes to an end? It certainly had lots of good points - resolution of the Percy/Annabeth/Rachel love triangle, background on the Oracle and Luke's troubled past, clever chapter titles, and another quest for Percy that takes him down a path few heroes have been brave (and foolhardy) enough to travel. Definitely read it if you've enjoyed the others.
