The Last Lumenian is a coming of age story of a 19-year-old sassy princess, Lilla, who is rebel-in-disguise, fighting for the refugee's freedom. The arrival of the mysterious and ruggedly-handsome Callum brings news of a bigger battle—the Era War between the two ruling archgods—that threatens not only Lilla's home world but everyone else's in the Seven Galaxies. Lilla must learn to control her magic and defeat the dark god before He finds her—the last Lumenian.
