Lily Ru and Rule Turner are in the process of planning their wedding when their enemy again tries to make sure they never live to reach their wedding day.

While Lily is trying to do her job with the FBI and Rule is trying to keep her safe as well as find out why a lupus went on a killing spree, Benedict Turner (Rules brother) has found himself face to face with his Chosen. But, how can he have a Chosen when he already had and lost one? The Lady never has given a man two, let alone a clan two, and they already have Lily.

Arjenie Fox is on a mission to prevent danger from comimg to the Nokali. With her special gift, she can walk right past a man without them even knowing she is there. So, how is it possible that Benedict has been able to see her not once but twice? When she is captured, it is up to her to protect those she loves but a handsome man like Benedict makes it very difficult to keep her secrets.

When they all find themselves fighting to protect not just their clan but all the Lupi clans, it leads them all into a danger that may cost them their lives. Will they survive or will their enemy finally win?

Eileen Wilks' latest installment of her Lupi Series, BLOOD CHALLENGE, lives up to its predecessors; full of intrigue, danger and romance. She continues her story of Lily and Rule but also brings a new couple together with Benedict and Arjenie. To get the full experience I would suggest reading the books in order but it is not necessary. I look forward to reading what is waiting for Lily and Rule in the next book. The Lupi Series is one of the best Were series I have ever read.
