From the back of the book:

"In 2784, General Aleksandr Kerensky led his loyal followers out of the Inner Sphere and into exile, far away from the strife and chaos of the Succession Wars.

In 2815, his son Nicholas founded the Clans.

In 3049, the Clans returned to the Inner Sphere, determined to avenge their forefathers and restore the glory of the long-vanished Star League.

This sourcebook gives a complete history and cultural description of Clan Wolf, one of the most prominent Clans and the one that bears the name of Kerensky himself. Included is a post-Tukayyid roster of the Wolf touman and personal profiles of important Wolf leaders."

User comment:

In addition to the background detail on the clan and it's personalities, this book introduced four new BattleMechs: the Linebacker, the Naga, the Phantom and the Pouncer. These 'Mechs would later be preprinted in the BattleTech Technical Readout: 3055.
