L.J. deVet is the author of the children's picture books James and his Boots and Teddy's Christmas Wish, and ALTOR: The Shadow Rebellion, a fantasy fiction novel for teens and young adults, also the first book in The Chronicles of Ageron.

Published in 2012, ALTOR: The Shadow Rebellion (The Chronicles of Ageron), a fantasy fiction novel for children, teens and young adults, was Louis's debut publication. The following year, Louis released his first children's picture book, Teddy's Christmas Wish.

Louis spent 2015 working on a new children's picture book, James and his Boots. Based loosely on imaginative adventures he and his cousin embarked upon during their youth, Louis adapted the story to present the limitless imagination of all children; something of which he has been exposed to as a teacher, and something he always strives to nurture as an author.
