Fate is fixed for those living in the world tree, Yggdrasil. Their cyclical destiny is carved in runes into the tree by the Nornir, three sisters who govern the past, present, and future.
But what happens when new runes appear - runes that cannot be changed and which foretell the destruction of the Nornir and all the nine realms of Yggdrasil forever?
Runes don't lie, but could they be wrong?
Skuld, the youngest of the Nornir, must find a way to uncarve this disastrous destiny. She undertakes a harrowing journey through the realms of the world tree to stop the one who dares defy the fate carved by the Norns before it is too late.
