The poet Persimmon Gaunt and the thief Imago Bone had sought only to retire from adventuring and start a family, but they never reckoned on their baby becoming the chosen vessel of the mystical energies of a distant Eastern land. With their son Innocence hunted by various factions hoping to use him as a tool, they kept him safe at the cost of trapping him in a pocket dimension of accelerated time.<br><br>Now free, the thirteen-year-old Innocence has rejected his parents and his &quot;destiny&quot; and has made dangerous friends in a barbaric Western land of dragon-prowed ships and rugged fjords. Desperately, Gaunt and Bone seek to track him down, along with their companion Snow Pine and her daughter A-Girl-Is-A-Joy, who was once trapped with Innocence too.<br><br>But as the nomadic Karvaks and their war-balloons strike west, and a troll-king spins his webs, and Joy is herself chosen by the spirit of the very land Innocence has fled to, Gaunt and Bone find themselves at the heart of a vast struggle -- and their own son is emerging from that conflict as a force of evil. To save him and everything they know, they turn to a dangerous magical book,<i>The Chart of Tomorrows</i>, that reveals pathways through time. Upon the treacherous seas of history, Gaunt and Bone must face the darkness in each other’s pasts, in order to rescue their future.
