Book 1

Prophecy Of The Sisters

by Michelle Zink

Published 1 March 2008

Without the Keys, something terrible will happen. Something that cannot be undone.
And with them, I might bring an end to the riddle of the Prophecy and my strange part in it.
If Alice and I are on conflicting sides of the Prophecy, the Keys would be dangerous in her hands.

Which means I have to find them.

And I have to do it before my sister.

This is the story of sixteen-year-old Lia Milthorpe's quest to discover her role and her twin sister's in a powerful prophecy that has affected twin sisters for generations. But nothing can prepare her for what she discovers - about herself, about her family, and about the danger that goes from haunting her dreams to becoming her reality.

Guardian Of The Gate

by Michelle Zink

Published 1 August 2010

Sixteen-year-old Lia Milthorpe must journey to the uncharted isle of Altus to continue her search for the missing pages of the Book of Chaos - the pages that could tell her how to end the prophecy that has turned generations of sisters against each other. But the journey will test more than just her courage, it will also test her loyalty to her beloved boyfriend, James.

Meanwhile, twin sister Alice will stop at nothing to reclaim Lia's role as the Gate. And that's not the only thing she wants from her sister: there's also Lia's true love.

The outcome of their battle could have consequences of Biblical proportions and, in the end, only one sister will be left standing.

Rise of Souls

by Michelle Zink

Published 1 January 2012

The Gate to the mortal world is finally closed. Lia Milthorpe has settled with her husband on Altus, the land that bridges the gap between the Otherworlds and the physical one.

Samael's banishment has brought prosperity to the land, and no one is happier than Una Whelan. For the first time in centuries, those who live on the island - including Una and her suitor, Fenris - can do so in peace. Or so they thought.

This novella reveals what happens to Lia, Dimitri, and Altus after Circle of Fire, the final book in the Prophecy of the Sisters trilogy. If you thought there was a happy ending, think again.


Whisper of Souls

by Michelle Zink

Published 1 January 2012

Before Prophecy of the Sisters, before Alice and Lia became pawns in the curse that turned sister against sister, the burden of the prophecy belonged to their mother, Adelaide. This is her story.

Adelaide Milthorpe is losing her grip on sanity. She is a Gate-a human portal to the Otherworlds, destined to bring forth Samael, the most powerful demon of all time, and his Lost Souls. Prowling the halls of Birchwood Manor, Adelaide is haunted by the whispers of the otherworldly Souls, who seek to use her for entry into the real world, where they would wreak havoc and rule beside their leader, Samael, in chaos. Their pleas plague her, torture her, tempt her. Samael calls to her, his promise of peace in the Otherworlds increasingly difficult to resist. And the stakes are high, for if Adelaide gives in to his urgings, her two daughters will inherit the same curse, forcing them to make the same impossible choice as they, too, are cast in the roles of Guardian and Gate.

In this novella that delves further into the Prophecy, Adelaide's struggle to reconcile her two worlds as she descends into madness will captivate fans of the Prophecy of the Sisters series and new readers alike.
