I read a book a long time ago and can only remember bits and pieces, but it's about a tribe of dragon people (main character being a young
I think they all have different dragon"powers" such as flying speed and fire breathing...and they can hide or "cloak" their wings maybe...
Thanks for asking! Did some searching around with different keywords - let me run Shana Abe's Drakon Saga by you. It's got the tribe of dragonkin living hidden from human society, the powers sound about right, and the protagonist is a young woman who can tap into those powers but was separated from her tribe and lived among humans. There are some unique things about the setting - it plays out in late Georgian/Regency England and Transylvania - and it'll have a lot of the usual fantasy romance elements, but Abe has a deservedly strong reputation.
If it's not quite the right fit, there are definitely other possibilities - Donna MacQuigg's Dragon's Secret, and even some elements of Robin Hobb's Dragon Keeper. So we can keep trying! Feel free to email back or call 402-444-4800 with additional questions.
