In the myths, Ouranos returned to the sky when Kronos castrated him. However in the books, it seems that Kronos' brothers held him down as they cut him to pieces. They also refer to it as murder in the book and even in the glossary, it says that Kronos killed his father. It is possible that Ouranos is truly dead, but there is a slim chance he is reforming. However we find out in The Titan's Curse that the sky still loves the earth, so he may not actually help if he is alive somehow.
