Here is the summary of the book:
After the all-out Eighth Day war in Mexico, Jax, Riley, and Evangeline have gone into hiding. There are still rogue Transitioners and evil Kin lords who want to use Riley, a descendant of King Arthur, and Evangeline, a powerful wizard with bloodlines to Merlin, to get control over the Eighth Day.
So when Finn Ambrose, a mysterious stranger, contacts Jax claiming to be his uncle, Jax’s defenses go up—especially when Finn tells Jax that he’s holding Jax’s best friend, Billy, hostage. To rescue Billy and keep Riley and Evangeline out of the fray, Jax sneaks off to New York City on his own. But once there, he discovers a surprising truth: Finn is his uncle and Jax is closely related to the Dulacs—a notoriously corrupt and dangerous Transitioner clan who have been dying to get their hands on Riley and Evangeline. And family or not, these people will stop at nothing to get what they want.
With suspense, action, and intrigue lurking around every corner, this fast-paced fantasy series will be a welcome addition for fans of Percy Jackson and Harry Potter.
An extra day of the week, Grunsday. Dianne K. Salerni wowed us with her first eighth day adventure in the first book of the same name. In this sequel titled 'The Inquisitor's Mark', we see of the next step in Jax, Riley & Evangeline's fight against the evil Kin and Transitioners. Just as action-packed and mind-blowing as the first. This leg of the series explores Jax's story and his family on his dad's side.
After the eighth day battle in Mexico Evangeline Emrys wants to find her only living relative, her sister. Fitting since these two are the only living Emrys left and the only source to keep the Grunsday spell alive. But Riley Pendragon & Evangeline Emrys are not really important this time as the Ambrose & the Dulac family comes knocking.
Jax's dad had even more secrets buried in his closet than we were aware of and I loved how Salerni was systematic about the whole ordeal. Disclosing her cards one by one. We find out what really happened to prompt Rayne Aubrey to cut this ties from his very influential family. A centuries old family, you would expect them to be set in their old ways. They are not at all picky when it comes to them using their powers to get what they want. But out of this whole orthodox lot Jax's cousin Dorian I liked best. He was always defying his family in minuscule ways possible, he knows his family is not really the greatest and he tries to work with that.
Jax, Billy & cousin Dorian were the heroes of this sequel. Them against their family. I loved how resourceful they were and how they used their knowledge to get out of sticky situations. They showed great courage and maturity in the face of adversity and I liked it very much. Dianne K. Salerni has put out an equally enjoyable sequel and you would be loathe to miss out on this Grunsday fun.
"Them against family. A sequel as fun as the first with an extra day of the week"
