The Aenigma Lights

Kate is a Keeper—a storyteller, magic-wielder, and researcher—but a single mystery has evaded her all her life: What happened on the tragic day when two strangers stole not only the puzzle box that hummed with magic but so much more? She and her brother Bo have searched for twenty years with no luck. Until Venn, a surly elf, shows up on the hidden doorstep of the Keepers' Stronghold with that same aenigma box—and a message that Bo has disappeared. Kate needs a guide back to Venn's homeland to search for him, and Venn needs to find him for reasons of her own.

Keeper Kate has spent weeks searching for her missing brother. Following his trail, studying clues, and using the mysterious aenigma box to help reconstruct the story of what had happened to him. But she's gotten the story dreadfully, catastrophically wrong. Now, faced with the losses and scars from her search, she and Venn must tackle a new obstacle: the elven White Wood and its ruthless king. In a desperate attempt to find her brother, Kate finds herself entangled in a deadly quest to find the Warden of the Wood—a search that will lead to her own death if she doesn't complete it in time.

Every step of their journey has brought Kate and Venn to new mysteries. Every answer led to new questions. Every victory led to new, troubling problems. In Lastlight, they have one more chance to figure out the truth behind the events of the White Wood, solve the riddle of Renault's cursed ravine, and finally open the aenigma box.
