The Book of Lies in Bloomington, MN

When humans' trusted allies turn on them, nowhere is safe...
For over seventy years, the use of familiars-monsters bound by magic to fight beside humans in the Long War-divided magery into two factions. Now, the monsters strike back.
As Helena prepares for the Conference of Neutralities, reports of familiars breaking their bonds to attack and kill their masters raise tensions between the factions to an unprecedented high.
Faced with the challenge of keeping her relationship with Malcolm Campbell secret from more than a hundred of her fellow custodians, Helena must also protect herself from rogue familiars-and they're closer than she thinks.
