I'm not too sure if there are many like it! It's quite unique.
However, 'Without You' by the same author is my favourite book by her, and has a very similar vibe, and manner, and characteristics in each role as Liliah. A different story line but with similar bits.
Another book you could try is Amazing Gracie, which I have loved for years. Any book in my 'best of the bear's category, or any book in my 'Top 5's' have amazing story kinrs, all of which draw me in. If you need me to put a good word in for a book of you're not too sure whether to read it or not, then I'm your gal :)
