Wanderer / Victor Kelleher.

In a dangerous world where predators roam both land and sea, an orphaned young boatman, Dane, wanders alone. Faced with the terrors of the water and the ever-present threat of a warrior group called the Clan, he struggles to survive.
Along with his precious kayak, Dane has one other treasure: a much-loved book given to him by his mother, which is a source of comfort in the hardest of times.
When he encounters Garth, a book-loving old boat builder, and his amazing granddaughter Lana, everything changes, as he and Lana are pitched into a perilous quest that challenges all they hold dear.
