The tenth city by Patrick Carman

"The land of Elyon book 3". It continues exactly where it left in the second book.
It's nice but nothing special. I liked the first one better, but this one is still better than the second.
They all go to save Yipes and defeat Grindall . They are on the ship, direction Lathbury. When the black swarm attacks, Armon hides underwater. Elyon's voice tells Alexa that only Catherine can stop in Lathbury, but they will have to continue their journey. They must turn their ship towards dangerous waters, where no one has gone before... many have tried to go that way looking for the tenth city but nobody has succeeded until now. They try it anyone because Elyon said so, and then when they are still struggling to keep the ship on its way Alexa asks Armon to swim ashore with her and to climb a cliff carrying her along. It's hard even for the giant but when they get to the top they take a look around and go down again. Elyon warns them to tell nobody what they've seen, and now they sail towards Ainsworth, where Armon takes Alexa Murphy and the wolf Odessa to the city, but the ship with the others on board are taken away by the wind. Alexa meets again Pervis and Nicolas, who knew already that Warvold was not dead. They go together to Bridewell where they find her father. Alexa goes alone to rescue Yipes and they escape through the tunnels where she gets stuck but Pervis finds her and helps her. Elyon's voice tells her that unfortunately her father will have to die in two days, and she's very sad but there's nothing she can do but go on. She's outside of Bridewell now. Pervis goes back to look for her father, and Walvold and Armon join her to continue their journey. Together they go to the forest council, where the forest is dying because of Abaddon's dark powers.
They talk to Ander the bear but then Grindall comes, Odessa lead him there. They are all captured and Alexa has to give him her jocasta, the last one. They all leave the forest together, heading towards the tenth city, through the Sly Field, in the big mist where they can find their way only using the jocasta : it casts a light only when pointed in the right direction.
When they get near their destination, Grindall is anxious to reach the tenth city and destroy it. In that mist Grindall can't see anything, while they are able to see just a little thanks to the light cast by the jocasta. Grindall orders his ogres to kill Warvold, so that he won't be able to see the city that he dreamed to see all his life. At this point Armon kills the ogre near him and then the ones that keep Yipes and Alexa prisoners. Grindall can't see him and is not sure of what is going on, but he can feel that he's very near his goal, so he orders his ogres to run towards the tenth city, to run onwards, along with the black swarm, they are all drawn to something ahead of them. They didn't know it but they were tricked by Alexa with Odessa's help. She never betrayed, of course. Alexa and Armon had seen what was there, and now Elyon's plan is fulfilled. Abaddon's little army runs through the mist and falls into the great pit where Abaddon himself is prisoner. Elyon then tells them to reach the tenth city, after the mist has disappeared; she has to give the last jocasta back, unfortunately. They greet again John Christopher, and then Armon goes over there with Warvold's dead body, so that they can say goodbye to him. Alexa learns only now that Warvold is her real father, and Catherine her birth mother, and that she was raised by Catherine's sister.
Now Alexa goes back with Yipes, Murphy Odessa and Squire flying over them. Soon they meet Nicolas and Pervis and James Daley, the man she's always called father. On horses they go back quickly, and in Lathbury she meets the two sisters, her two mothers: "They were worried that I might not love them anymore. Sometimes adults can be silly that way".
Of course she feels the same love towards them.
One years passes, Yipes is still with her, and Roland comes back. He's Warvold's brother, and when he goes away again Alexa and Yipes go with him, looking for new adventures, Alexa and Roland together like true Walvolds.
