Looking forward to the annual Samhain party, Isolde opens a letter - and instantly endangers her whole family. The hunt is on for who threatens to kill her - and why. As she tracks through the archives of past Lawspeakers, Isolde discovers her dam's secrets. Tied by something she did at her daughter's birth, she realises, too late, what it will mean for Michael if she dies. Everything is getting personal - from the intrusion into their home by malign magic to Michael being challenged to a duel by one of the greatest magicians in the UK. Even the party becomes a threat as Declan is pursued by a reporter determined to find out his secrets. Hunted by the Inquisition, Isolde and Michael face life - or death - in jail. But first they have to face the wrath of the Magicians' Guild.
