Sarah, Nathaniel, and Lily resist unconditional love as they feed primal desires. Not believing the possibility of having it all, they struggle to believe that they, the “least of these”, rightfully deserve a lifetime of love and happiness– Especially with how graphically and unconventionally they choose to express themselves.
Each of the characters comes to realize how tortured their lives have become. Violent images, dreams, and actions occur as they spiral downward into their dark lives. As they each reach a personal impasse, they must decide how they will make their lives better. In the process, they must also mend broken intimate relationships with the ones they love.

This erotic, edgy tale describes and embraces elements of s/M lifestyle. Their personal proclivities are not condemned.

If a fish does not have fins, it becomes lifeless and sinks helplessly to the bottom of the water.

Humans are exactly the same way.
