Michael J. Sullivan garnered critical raves and a massive readership for his Riyria Revelations series. The first book in his highly anticipated Riyria Chronicles series of prequels, The Crown Tower brings together warrior Hadrian Blackwater with thieving assassin Royce Melborn. The two form a less-than-friendly pairing, but the quest before them has a rare prize indeed, and if they can breach the supposedly impregnable walls of the Crown Tower, their names will be legend.

Unable to get her out of his mind, the two thieves return to Medford but receive a very different reception - Gwen refuses to see them. The victim of abuse by a powerful noble, she suspects that Royce will ignore any danger in his desire for revenge. By turning the thieves away, Gwen hopes to once more protect them. What she doesn't realize is what the two are capable of - but she's about to find out.

When the last member of the oldest noble family in Avryn is targeted for assassination, Riyria is hired to foil the plot.

Three years have passed since the war-weary mercenary Hadrian and the cynical ex-assassin Royce joined forces to start life as thieves for hire. Things have gone well enough until they receive the odd assignment to prevent a murder. Now they must venture into a forgotten corner of southern Avryn - a place whose history predates the empire. As usual, challenges abound as they try to anticipate the moves of an unknown assassin before it's too late.

But that's not their only problem. The countess of Dulgath has a dark secret she's determined to keep hidden. Then there's the little matter of Riyria's new employer...the Nyphron Church.
