In book four of the Kaiser Haus series, Maximillian finds himself incarcerated deep in a dungeon cell. Questions regarding his mental stability have placed him in danger. When the House doctor determines the "Priceless" collar is 'irreparably damaged' Master Peter is forced into a decision he will live to regret. Unexpectedly uncollared, desperate, and facing sure death, Maximillian also makes a terrible mistake. He chooses to accept the Elder Jonas's offer. This results in a fate almost too horrible to imagine. Maximillian trades in his single abusive Master, only to become subjected to five of the most despotic souls to ever walk the halls of Kaiser Haus.

As the Elder's shared property Maximillian is recollared and renamed. Now called Mad Maxx, he finds himself caught in the paths of twisted plots and deadly vendettas that span decades.

Determined to complete "the mission" Der Hund splits the Max shards and Christian into teams. Each 'shard' is tasked with doing whatever is necessary to assure 'the boy' survives long enough to break his collar.

Mad Maxx's onsetting madness grows in strength as he endures brutal tortures, bizarre fetishes, and vicious sexual assaults. The shards surprise the disfigured Der Hund and each other as old enemies become valuable allies.

Despite their perilous journey of murderous mayhem, the shard Mad Max reclaims a treasure Der Hund believed lost forever. Unconditional love blossoms within the "Priceless" as he follows his inner lamb in search of the "green fields" of redemption.
