You & Me at the End of the World by Brianna Bourne
 
Hannah and Leo wake up to find their entire city eerily silent and completely empty. Forced together by isolation, they navigate a world without rules, discovering who they truly are when no one is watching. However, they soon realize their harmless-looking paradise holds a dangerous secret that could tear them apart forever.
