Avatar: The Last Airbender: The Search, Part 1-3

For years, fans of Avatar: The Last Airbender and The Legend of Korra have burned with one question—what happened to Fire Lord Zuko's mother? Finding a clue at last, Zuko enlists the aid of Team Avatar—and the most unlikely ally of all—to help uncover the biggest secret of his life.

I have been waiting a long time to read this series. I have wanted to know about Zuko's mother since I first started watching the show and I hated how it ended on such a cliffhanger in that regard. 
First off, the drawing is beautiful as well as the writing. I could hear the characters voices so clearly in my head...especially Sokka. 
I love how the book begins in the past by showing the reader where his mother came from and what her life was like before. It continues to alternate between past and present with Zuko and the gang following the clues to find his mother. It ends with a crazy twist of a cliffhanger though so I suggest buying all three books like I did so you don't have to wait. 

Enter the Forgetful Valley
As Fire Lord Zuko continues his quest to uncover his mother's fate, a shocking revelation causes him to question everything he knows. It's an opportunity that his sister, the deadly and insane Azula, will not fail to take advantage of as she joins Zuko and his friends, Aang, Katara, and Sokka on their journey into a mysterious forest from which some people never reemerge...

In this second novel, we learn more about the purpose of the wolf spirit and continue to uncover more about Zuko's mother and her journey. If you think that you hate the Fire Lord from the show just wait until you read The Search Part 2. You might love to hate him even more as the story shows more of his cruelty behind the scenes. 

The Fate of the Fire Lord!
Avatar Aang travels to the spirit world to parlay with an ancient power, bringing Fire Lord Zuko ever closer to discovering the truth about his mother's fate—and his own past. Yet Zuko's sister Azula is becoming increasingly dangerous, threatening to ruin everything that Zuko, Aang, Katara, and Sokka have struggled to achieve on their search!

In the final installment of The Search, readers are finally told what became of Zuko's mother. With so many twists and turns I was surprised when it was revealed. The book held revelation after revelation. If you think you know what is going to happen you might be surprised. I loved part 3 the most because of the closure. I actually breathed a sigh of relief when I was done because I finally had all of the answers that I was looking for. My husband read them with me and said that he thought that the ending was rushed which is slightly true but it didn't bother me. I think that all of the fans of the show will be happy with how these books carry on the story. I kind of wish that Zuko's mother could just have her own book.
