Fox and Wolf
This book can be downloaded and read in iBooks on your Mac or iOS device.
Yuki Yamakawa comes from an old yakuza family. She loves training dogs and beating up bullies for a more secret reason: she's a werewolf. After one fight too many, Yuki's uncle sends her to Osaka's most exclusive girl's school to straighten her out.
There she meets her exact opposite, Ami Tokudaiji.
Ami is as high in society as Yuki is low. But with her family threatened by a financial scandal, the Tokudaiji fortune depends on Ami's mother breaking the law in a shady real estate deal. Just as Yuki's estranged father returns to Osaka to launch a criminal investigation.
As it turns out, on her father's side, Yuki's blood runs bluer than any of her aristocratic classmates. Even so, that long-hidden family connection pales in comparison to the most fantastic fact of all: Ami is a kitsune, a Japanese werefox, and doesn't even know it!
When the two of them end up in the same homeroom class at school, Yuki is determined to make Ami her new best friend. That is, if they don't kill each other first.
