I've enjoyed most of the adult-themed Aimes books. Her big downsides are (a) she REALLY needs a good copy editor for her typos, and (b) she sometimes mixes in non-braces related fetish stuff that seems out of place.
Her books that I've enjoyed, ranked:
1. Notwithstanding Braces
2. Bracing Times with Cecilia
3. Braced in Wedlock
4. Love and Braces
5. Living the Braced Fantasy
I agree that some (most?) of the treatments are fanciful, and the scenarios are often unrealistic. I'm okay with that, especially since she's the only game in town.
I am on the fence about the newest book. I'm sure I'd enjoy reading about the mother's braces experience, but the daughter part holds zero interest for me.
