Female Friendship Book

Hi! My beautiful best friend is getting married in a couple weeks. The bridesmaids have decided part of our gift will be a book as she loves to give/recieve books & is a big reader. I'm looking for suggestions where the main message voices the importance/significance of friendship. She's pretty nature-ey, loves animals, grew up on a farm, appreciates beauty, & is highly empathetic, if that helps spark some ideas lol! I'm open to non-fiction, novels, coffee table type books, & even illustrations books. Please let me know what you think! 🤗
