If you like Claire's work (and what's not to like?) I can recommend these books, Desk and Daisies. Both books collect Wendling's development work, as well as final colour renderings that can be found in Daisies. They are still in print and, for now at least (at the time of this post), easy to get hold of online.
In my opinion Wendling is about as good as it gets. You can learn a lot from studying her work.
