London from my windows / Mary Carter.

Enhanced descriptions from Syndetics:

Ava Wilder's home in small-town Iowa is her sanctuary. A talented sketch artist with severe agoraphobia, Ava spends her days drawing a far more adventurous life than her invisible disability allows. Until she receives a package from London, explaining that she has inherited her Aunt Beverly's entire estate-on condition that she lives in Bev's West End flat for a year.

Once overseas, Ava wonders if she's simply swapped one prison for another. The streets and shops are intimidating, and Bev's home appears to be a drop-in center for local eccentrics. Worst of all, Bev left a list of impossible provisos to be overseen by her quirky, attractive solicitor. Ava is expected to go out-to experience clubs, pubs, and culture; to visit Big Ben, Hyde Park, and the London Eye. After years of viewing the world through a pane of glass, she's at the messy, complicated center of it. As exhilarated as she is terrified, will she be able to step up, step out, and claim the life she was meant for?

In an insightful, poignant novel, Mary Carter delves deep into self-discovery and the meaning of courage, exploring the fears that serve to protect us-until life calls us to connect at last.
