Precious Thing by Colette McBeth

Rachel has put her traumatic childhood behind her and is a successful television reporter in London. However, she is shaken when she realizes that the missing person report she's about to deliver on-air is about her childhood best friend, Clara.  The two haven't been particularly close in the last several years, but had recently reconnected. Rachel wonders what's happened to Clara, but when CCTV footage is obtained by the police that shows Clara with Rachel's boyfriend, Jonny, on the night she vanished, Rachel is forced to think differently about the disappearance. Interspersing scenes from their teenage years with the hunt to find Clara, the reader sees the dark nature of their friendship.
