Four tiers trade in a perfect balance on the massive spire that comprises the Vertical Horizon. Four magic truth stones maintain that delicate balance, fostering goodwill and restraining evil, until one is stolen, and the Realm is plunged into war.
Princess Aratess longs to be a King’s Bowman, sworn protector of the Realm. Bowman Tate Hawthorne, a Reyjik outsider, longs to prove himself worthy of that very uniform. Outside the castle, when the seaward tier of Reyjik overruns the tierdom of Costair, Tate and Tess must escape skyward, warn the King of the Realm, and mount a counterattack, but not before enlisting the help of Deacon, Tate’s childhood friend and lighter-than aircraft pirate.
Will Tate, Tess, Deacon, and a crew of pirates prove enough to stave off invasion and turn the tide of war?
Who will win the princess’s love, and does she have the heart of a Bowman?
