The Hummingbird Dagger by Cindy Anstey

When his younger brother takes the carriage and careens out onto the roadway at high speed, James shouts at him to slow down but he doesn't hear him.  When Walter hits the bridge, he also hits another carriage and both fly off the bridge.  James races down on his horse and sees his brother and his friend have not been injured.  The other carriage had a young woman in it and she's been injured.  The driver and his companion are recovering but she's not moving.  James demands that she be relinquished to him so he can take her home and have the doctor see her.  The men try not to give her up but he takes her anyway.  He doesn't know how much trouble he's just brought upon himself...

Macmillon Children's Publishing Group and Net Galley let me read this book for review (thank you).  It will be published April 16th.

When she wakes up, she doesn't know her name or anything about herself.  She also doesn't remember what happened to her.  As they try to help her remember the past, they find themselves meeting some shady characters.  They must have been used in the kidnapping or why would they be interested in her?

There are lots of characters, some good and some bad.  James and the young woman are falling love.  But they are trying to kill her now and he has to find somewhere to hide her.  He tries but she's found anyway.

When her identity is revealed, she's still not remembering them.  It's only when she visits a warehouse that part of it is coming back to her.

I was totally surprised to find who the mastermind of the plot was.  It ties it together and solves the mystery but it's not happy ever after for all.

The story reads like an old classic mystery novel and I enjoyed it.  Just watch out for that dagger...
