The Sister - Louise Jensen

Grace, Grace's boyfriend Dan, and Charlie have been friends since childhood. But one day Charlie leaves without saying goodbye. For years she sends Grace postcards from all over the world. Then one day she reappears in Grace's life, but before they get a chance to talk, Charlie dies. Grace is left with her mysterious last words “I did something terrible, Grace. I hope you can forgive me.” She has no idea what Charlie did, but she's determined to find out and she's also determined to find Charlie's father, something Charlie wanted so desperately to do. Grace and Dan turn to social media to search for him or to find someone who knows him. A girl claiming to be Charlie's half-sister responds and meets up with Grace to talk. That's when things start to fall apart for Grace.

This is an excellent debut novel. It's well-crafted. There is the right amount of twists and turns, and they're good. It alternates between then and now and flows well. The characters are three-dimensional, what happens in their lives and how certain situations changed them is believable. I really enjoyed it!
