1. Jane Austen
I'm a big Jane Austen fan, and even though I already have multiple copies of each of her books, I can't help myself whenever I see a pretty new edition I don't have yet. Austen's name is definitely one that appears a lot of times in my book collection, whether it's different editions of her own work or adaptations or retellings of her stories!
2. J.K. Rowling
I own all the Harry Potter books, so that already makes 7 J.K. Rowling titles. I do own several editions of some of the parts, and I also have her other books, including the ones she wrote under a different name, which I think at least counts for half in this list!
3. Lindsey Kelk
I love love love Lindsey Kelk's books. Her 'I Heart...' series is simply fabulous, but next to the 6 parts of that particular series I also have copies of all the other books Lindsey has released so far.
4. Carole Matthews
Carole Matthews has become one of the household names within the world of chicklit. She has released more than 24 books, and I think I own at least half of them, and am still adding to that collection!
5. Meg Cabot
I fell in love with Meg Cabot's 'The Princess Diaries' book series when I was young and over the years I've continued to read her amazing books. She has some great series for all ages, and I still can't get enough of her writing.
6. Ann M. Martin
There were no books I loved more than the Babysitters Club series by Ann M. Martin when I was a little girl. I've saved all the copies I ever bought and there are quite a lot of them!
7. William Shakespeare
8. Alexandra Potter
Alexandra Potter was one of the first chick lit authors I fell in love with when I was a teenager, and I remember walking around book shops, searching her novels. I have all of them (11 in total, I think), which gives her a place on this list as well!
