Moreover,she has found a safe way to communicate with Earth without Zeus knowing about it but things back home are not the same.Law is the President of the United States until his mother recovers from a heart attack and he seems distant towards Ari.On Earth,they expect Zeus's next step which is declaring war but they can't let that happen.So they ask from Ari to kill Zeus once and for all.In the beginning she hesitates but when Zeus orders that one human will be executed every day in order to take over Earth,she's more than happy to oblige.
Zeus is one crazy and paranoid person.He's getting older,weaker,starts losing control and he knows that.That's why he tortures Ari so that he can get as many information he can and find out weaknesses about humans.But at some point he crosses the line and the only to fight back is one: REVOLUTION
But apart from Zeus and his evil destruction plan,there's also Ari and Jackson.Ari can't forgive him for all the things he kept from her in Gravity.She's not ready for a relationship with him and he agrees with that but wishes for more.But throughout the book Ari uncovers secrets and truths about Jackson and the cruel way he was raised that makes her realize that she can't live without him.
Melissa West in Gravity introduces us to a new world.In Hover this world is about to change.Well hidden secrets,revelations,action packed and an unexpected cliffhanger that you won't see it coming makes Hover one of the best sequels I've read and I can't wait to read the final chapter of this story in Collide.
