Has Anyone Read The "WOOL" Sci-Fi Series??

One of my friends recommended it the other day and I have never heard of it. Have any of you read it? 


Thanks 


 from wiki:
The story of Wool takes place on a post-apocalyptic Earth. Humanity clings to survival in the Silo, a subterranean city extending hundreds of stories beneath the surface. There is one paramount law within the Silo: never say you want to go outside, for if you do, you will get your wish.
Wool initially follows the story of Holston, the Silo's sheriff. Holston spends the novel processing and investigating the circumstances surrounding his wife's death. Holston's investigation of the Silo and the secrets it holds ultimately serves as a catalyst that begins to impact the lives of various characters and sets up the action for the rest of the series.
Wool 2 continues the saga, this time following the unique relationship of Jahns, the Silo's mayor, and Marnes, the Silo's deputy. Their relationship is explored as they pursue a quest that leads them deeper into the lower levels of the Silo, and ultimately brings them into conflict with the Silo's IT division, whose growing authority is revealed. Their journey ultimately introduces them to Juliette, who will play a central role in the following stories.
Wool 3 through Wool 5 continue the saga, as Juliette continues to explore the mysteries of the Silo, bringing her into contact with the head of IT and Lukas, a young artist. The growing relationship between Lukas and Juliette serve as a backdrop for the remaining three novellas, as the mystery of the Silo is gradually revealed.
