Daydreamer — Susie Tate

As a scruffy, disorganised daydreamer, Lucy Mayweather is like a fish out of water at the high-powered offices of her brother's billionaire best friend. When she agreed to work for Felix, she had no idea quite how cut-throat his world -- or he -- would be. She just wanted to escape her reclusive life and be close to her childhood crush, hoping he might notice her.

But Lucy's lonelier in London than she's even been in her tiny village back home. The boy she grew up with has been replaced by a powerful, ruthless, extremely attractive man who doesn't tolerate incompetence and who no longer seems to find Lucy's quirks cute. Instead, he lectures her almost daily on her general crapness, and seems blind to the bullying she endures from his colleagues.

For Felix, agreeing to employ Lucy was a mistake. This shy bookworm with her head in the clouds, who wears tattered jumpers, carries multiple pens in her hair and has an obvious crush on him must be by far the worst assistant in London. But he's always had a soft spot for the quirky little girl who lived in her own world and told the best stories. Well, now that little girl is all grown up… and he can't stop thinking about her.

After Felix gives in to his bone-deep longing for his best friend's little sister, he starts to feel more than he has in years. But Lucy has secrets, and Felix has trust issues. When his inability to trust her leads to a terrible betrayal and places Lucy in danger, Felix is faced with losing her forever. Because the new, hardened, traumatised Lucy is nothing like the daydreaming pushover she once was…

This is a full length, brother's best friend, grumpy billionaire boss romance.
