Review: Destined by Aprilynne Pike

For those of you who haven't read this series yet, (a) you should have, (b) don't let the whole 11+ thing put you off, because simpler writing has its benefits, and (c) this is the last one in the series, so you might not wanna look at this review. Sorry.
 We all know what we're waiting for in this book: Laurel to make her choice between David and Tamani. But all sorts of other stuff is going on too -- they've finally determined Yuki's caste and gotten her caught, but Klea's still out there, and the both of them bode seriously ill for the whole of Avalon. Can Laurel, Chelsea, David and Tamani (with the help of Shar and Jamison) save the world from Klea's tyranny... and save themselves?
