Shifting Sin

by Rachel Starkie

Originally published as Seduced by Sloth, Shifting Sin is a reimagined expanded rewrite of Rachel Starkie’s sexy and adventurous take on the Seven Sins. Lùcas MacAilein is the youngest of the Seven Sins. Released upon the world, he has tried to withstand the power of Sloth for many years, leading to many interesting, if not odd, habits just to stay away from the darkness.

In the midst of building relationships that may be his saving grace, he discovers that his baby sisters have been taken by their Mage father, and he has no choice but to embrace the darkness and seek the help of his sinful siblings to save the girls.

Will the help of his best friend, Techwitch Gizmo, and an emerging group of mates be enough to keep him on task, or will his sin overcome him and drag him into the abyss from which there is no escape for him or the rest of mankind?

Hell only knows and it is not giving up any secrets...

Lucas is sooo adorable

Lucas is probably one of my favourite characters, hes hilarious, adorable and oh so crazy!
When his sin is taking him over hes determined to ensure those he cares about are safe and happy first... but his mates and family will not let him go that easy... even if he is a pain in the a..

Also the little crossover to zuko is just...
