Books acting as portals to libraries around the world, transporting magical knights through them in order to save the world?

Yes, please!

Guardian of Secrets is the second book in the Library Jumpers series, and definitely not the one to start with. There's too much going on, too many characters and plot threads already happening at that point--and book 2 takes everything to an all new level. A major character's going to be under a spell, other characters aren't going to make it into book 3, and Gia's going to be involved in a significant love triangle--so. Much. Going. On. I feel like I need another week to process it all...and I should probably re-read before book 3 comes out...

Rating: 4 stars / B+

I voluntarily reviewed an Advance Reader Copy of this book.
