The Ironwood Tree

First, Simon is taken by a group of foul-smelling goblins. After that, a group of elves tries to trap Jared. Why is Spiderwick's Guide so sought after by the faerie community as a whole? And now that the Guide has vanished for no apparent reason, will the Grace children be left on their own? Never rely on it.

The ancient, abandoned quarry at the edge of town is indicated by hints. There's an abandoned mine that the dwarves have taken over. The faerie community is also aflutter with the news that a monster with grand ambitions for the planet has offered them a gift to join him: a queen.
