Bestselling fantasy writer Holly Lisle brings us her children's debut with a lyrical, fast paced fantasy for middle-grade readers! Mankind is Sunkind And rules by the light; Nightlings are Moonkind, And rule in the night; Or there will be war. Human and Nightlings are never to meet, but when Genna and her brother Dan venture into the old forest at night, they encounter a Nightling slave who reveals a terrifying Genna and Dan's village chieftain has made a dangerous deal with Letrin, ruler of the Nightlings, offering the lives of his people in exchange for his own immortality.

In the powerful, lyrical follow-up to THE RUBY KEY, Genna must master her new powers and summon an ancient magic to save her people in the fight for their freedom. In the battle between nightlings and humans, it's prophesied that the Sunrider is destined to unite the magics of the sun and moon for the good of all. She alone can lead the fight to defeat an immortal evil. Genna is the chosen Sunrider, and under nightling protection, she must learn the acient magics so she may bring an end to the war between slaves and masters. When she escapes a brutal plot concoted by the evil kai lords, Genna finds herself cast into the depths of the Sun Wizards' world.
