With her indomitable style, New York Times bestselling author Maria V. Snyder returns with an electric new fantasy series that will keep you on the edge of your seat.

'It's suicide, Shyla. You're the prize they want.'

Through her courage and tenacity, Shyla Sun-Kissed has awoken the power of The Eyes of Tamburah. But this feat only marks the beginning of the challenges that the magical order, the Invisible Sword, faces to free the underground city of Zirdai.

Though they have allies among the monks and splinter cells inside the city, Shyla knows the Invisible Sword doesn't have the strength to win. With the group fracturing due to the strain of losses from their latest ordeal, thinly veiled suspicions and endless disagreements, it's up to Shyla to forge a new united order.

When both the draconian Water Prince and brutal Heliacal Priestess learn of Shyla's new powers, life becomes even more complicated as they will stop at nothing to capture Shyla and take the magic of The Eyes for themselves. Hunted at every turn and unable to hide, Shyla and the Invisible Sword must use every resource at their command - and unearth new ones - in their race to save the city from destruction. But their enemies always seem to be one step ahead. And the cost to win the battle may be more than Shyla would ever be willing to pay...
