Oh wow. Happy ending!
How about Steal ( as in steal my heart) or Steel.

Kid stood out in the field with him this morning and tried calling all three names to him: Cinder, Storm and Orion. Horse turned and looked at her when she said Orion, but started walking towards her when she said Storm. She gave him a big hug and welcomed Storm into their family.
Thank you for all the suggestions, she loved the process of picking his name and getting to think about all the choices. As I said before, this is a kid who wanted suggestions and wanted to hear options because she wasn’t sure if Storm was the right name in the beginning, but now she knows for sure.[/QUOTE]
good; i was going to say that stormy was fine, and could always graduate to storm if need be. 
First thing that came to my mind was Gunner
