Under My Skin

2014

Everyone wants to either be a member of the Guild or work for them. Little does the populace know that the Guild hides sinister secrets... For Tate Sullivan, life in her small, coastal town is far from glamorous. The affluent lives of the Guild members and their servants isn't something she has ever wanted. But all sixteen year-olds must take a simple test, and Tate's result thrusts her into the Guild's world, one where they hide horrible plans for those they select. Tate must fight the relentless General Dagon for control of her mind, body, and soul to keep the one precious thing she has always taken for granted: herself. Her only ally is the same handsome boy she is pitted against in General Dagon’s deadly game. Quinn desires nothing more than to end the life of General Dagon who has taken over Tate's mind. While romance blooms between Tate and Quinn, General Dagon plots to eventually take over Tate's body, and love might end before it even begins.

Deep in My Bones

2019

After facing one of the most devious military minds in Myrian history, Tate Sullivan has removed the man who tried to take over her mind and body. Now she controls General Frederick Dagon’s affluent estate and has all the benefits of his high rank within the Guild. Life should be perfect. But all isn’t well. Tate finds herself still tormented by the relentless man she thought she’d outwitted. Dagon taught her to anticipate her opponent's actions, to predict every nefarious scheme, but behind the scenes more enemies are lining up to take away the freedom she fought to achieve. Can Tate rely on her inner strength and the love from Quinn Belfry, the General’s Master of Blades, to defeat her greatest enemy? Or will her greatest adversary, who hides behind the Guild, bring Tate under their control forever? Deep in My Bones is the stunning sequel to Shawntelle Madison's Under My Skin, the first title in her Immortality Strain duology.
