Girl Online by Zoe Sugg

I had no idea GirlOnline would take off the way it has – I can’t believe I now have 5432 followers, thanks so much! – and the thought of opening up to you all about this is terrifying, but here goes… Penny has a secret. Under the alias GirlOnline, she blogs about school dramas, boys, her mad, whirlwind family – and the panic attacks she’s suffered from lately. When things go from bad to worse, her family whisks her away to New York, where she meets the gorgeous, guitar-strumming Noah. Suddenly Penny is falling in love – and capturing every moment of it on her blog.
