Seth has been torturing Solin to get him to reveal the location of the key to Mt. Olympus. Lydia, a woman who Solin has taken care of since her mother passed away and thinks of as his daughter decides to take on the mission to save Solin and she trades places with Solin while he goes to retrieve the key for their freedom. While Lydia spends her time as prisoner to Seth she begins to see that there is much more to him than others think and she finds the man he hides from them all. He is not a bad man. He is only doing as he is made to. As Noir's guardian he must do things that he does not want to do. Rejected, betrayed and made into a slave all of his life has made Seth mean and untrusting but Lydia vows to show him the love and understanding that has been missing from his life.

Watching the two develop and embrace their relationship was a beautiful read. I love seeing Seth become the man that Lydia sees and knows is in there. I enjoyed Lydia she is a strong woman who cares deeply for the ones that she loves and will do just about anything for them. Seth is a good man who just needed the right woman by his side and Lydia is just that woman. Lydia and Seth not only must learn to trust one another but they must also fight for each other. Seth has gone through so much yet he still keeps his humanity, which is what Lydia sees and wants to bring back fully. I loved that these two were not afraid to give their hearts even knowing how much it might hurt.

As with all of Sherrilyn Kenyon's previous books, THE GUARDIAN comes with all the sarcasm and action she can pack into it. Making this a nice addition to the Dream Hunter's series. I think that each storyline whether it be the Dark Hunters, weres, or the Dream Hunter's, has its own balance and style. While they all fit together in this wondrous world they each seem to read a bit differently. While I did enjoy this book it is not one of my favorites in the series. I would have liked a bit more at the ending which seemed a little rushed and more information on how the key comes into play in this world would have been nice.

THE GUARDIAN is a great installment in the series and has me eagerly awaiting the next book to see what Sherrilyn Kenyon comes up with next for this world.
