The Ice Mage by Julianne Munich

Marcel lives with one foot in each world. The first world feels as harsh and cold as the ice he casts from his fingertips. They want to use him as a bloodless and efficient weapon, nothing more. The second world is home to three friendly passengers who charter his coach for a journey. Luc, Emilie, and Adelaide are happy to travel to a prince’s castle as retinue servants, while Marcel's heart sinks in guilt and dread with each step his horses take. Luc's amnesia spell is all that separates the good man he's become, from the evil killer within. The coachman is driving him to where his spell will be broken—and his true self will be unveiled. Marcel is faced with a terrifying dilemma of his own. Either obey the orders of Le Conseil Suprême and become their henchman—or die a traitor. All the while, his feelings for a forbidden woman tempt him to risk it all.

SPFBO8

Book 1 of the Mages in the Mundane historical fantasy series. He was a prince, forced into a new life as a pauper. Luc, a poor but vain young man in 1775 Paris, is confused by his dreams of gilded ballrooms and unknown people in lace and jewels. What's more, everything before the past two years is a hazy fog in his mind, and Aunt Mathilde gives him few answers. What he doesn't know is that 'Aunt Mathilde' is in fact his mother—a Sorceress. She keeps him captive under her magical veil, desperate to both protect him and to punish him for the evil deeds of his royal past. When disease leaves Luc scarred and weakened, he feels his life is over. He pushes away his humble friends, including Emilie, a young housemaid with inner beauty.

Emilie, scarred from smallpox, is resigned to life as a spinster. Yet, she sees beauty and joy in life and understands Luc's despair beneath his bitter, beastly attitude.

Unless Luc can embrace his inner strength, care about others, and love unselfishly, he risks destroying himself once more. An adult twist on Beauty and the Beast, with family drama, a secret underground society of Mages, and a sweet love story.
