Castle Glower, the royal residence of Sleyne, is a sentient, living entity that makes its wishes known in no uncertain terms and selects and protects the royal family. The Castle is up to its usual tricks, adding and removing rooms and features on Tuesdays. One morning Princess Celie, who knows Castle Glower better than anyone, is on her way to the schoolroom when the Castle suddenly adds a staircase leading up to a new, roofless tower. The curious young princess climbs stairs where she finds a large nest with an enormous, flame orange egg in the middle. She runs down to tell her family, but returns to find the staircase has disappeared. Castle Glower will allow no one else to see the stairs or the tower, but Celie is drawn repeatedly back to the tower where she wonders about and watches the egg. She is shocked and thrilled when it hatches to reveal a baby griffin. Celie can hardly wait to show her family, but the Castle makes it plain that she is to keep it secret. Then the Castle routine begins to alter, with changes coming more and more frequently, changes that are often dangerous and always puzzling. A strange wizard arrives to help Royal Wizard Bran determine what is happening to Castle Glower and why. These factors come together to provide clues to the Castle's mysterious past, but no one seems to know how to stabilize the Castle, and Celie and her family fear that the Castle is being attacked in the other world where it originated and where much of it still remains. How can a young girl raise what she always thought was a mythical creature without making others suspicious? Is the griffin's appearance related to the disturbance in Castle Glower? And most importantly, how can they help the Castle?
This second tale in the Castle Glower series is highly entertaining, and I would have loved to give it 5 stars. However, but rates only 3 because it violates my cardinal rule of writing: "Thou shalt not force a reader to continue to another book to gain closure to a story." I have no problem with series books that point to a sequel provided that they resolve the specific conflict in that book, aka the Harry Potter series which had the ongoing struggle between Harry and Voldemort but always resolved the main conflict in each book, e.g., the quest for the Sorcerer's Stone, the basilisk in the Chamber of Secrets, and so on. That does not happen in this book. Readers are left with a total cliffhanger, no answers for most of the major questions, and no resolution. I eagerly await the next book, but hope it will have a real ending rather than being another installment in "The Perils of Pauline," or rather, "The Castle Catastrophes."
