Dreams of Mariposa

Every decade, Marie must leave her home and everything she loves to start anew. She can't risk the locals learning the truth of her immortality, much less her vampiric need to feed off fear. Fortunately for Marie, fear comes easily, and she spends her endless days mourning the loss of her beloved.

When she is summoned to the leaders of the masquerade, she is persuaded to assist them in uncovering a mystery of powers possibly more ancient than their own order. As a rare daywalker of exquisite beauty, there is no society she cannot infiltrate. Having spent the last few centuries growing into her power, she expects to learn of the old powers then return to her lonely eternity of mourning.

She doesn't expect to fall in love, and everything changes.
