Flight of the Gargoyles - Gargoyle Guardian Chronicles, #4

To protect gargoyles, Mika must journey far from safety. As a gargoyle guardian, Mika Stillwater is determined to help every gargoyle in need. The problem is knowing where to find them. So far, she's relied on word of mouth, luck, and far too often, rumors to guide her. The gargoyles deserve better. Which is why Mika has set her sights on the everlasting tree and its special magic: Once a generation, it unleashes a flurry of seeds, each a magical clue destined to guide the recipient to the answer to any question they ask.
With the everlasting tree poised to bloom any day, Mika has an extraordinary chance to help untold gargoyles. But the tree is far from Terra Haven, and with the countryside full of hidden dangers, it's easy for a city-born human-and her gargoyle companion-to be snared by perils they never see coming .
