My Not So Perfect Life by Sophie Kinsella

Let's finish off the summer with a fun chick lit read. Part love story, part workplace drama, this sharply observed novel is a witty critique of the false judgments we make in a social-media-obsessed world. Everywhere Katie Brenner looks, someone else is living the life she longs for, particularly her boss, Demeter Farlowe. Demeter is brilliant and creative, lives with her perfect family in a posh townhouse, and wears the coolest clothes. Katie's life, meanwhile, is a daily struggle--from her dismal rental to her oddball flatmates to the tense office politics she's trying to negotiate. No wonder Katie takes refuge in not-quite-true Instagram posts, especially as she's desperate to make her dad proud.
