Iona thought, Islands are bumping together atop the water? Putting her curiosity aside, Iona knows she doesn't have time to linger. Arrowanna is turning 16 and feels nothing but frustration from the "gift" she's been given. She does not want to leave her magnificent tree home. Surprises, action and adventure take off as Arrowanna boards the magic tall ship and sets sail to fulfil her promise. But Vikings, Draugar, and a Berserker are making things extremely difficult. An underwater battle will have you holding your breath. Twists and turns through the ice caves will have you chilled to the bone with suspense. Will Iona and Arrowanna ever cross paths? Will Thassalon recover? And what about Erland? All Iona has to do is carry out her assignment and head for Planet Sky, but the likeliness of doing so is looking slim.
