You can always create your own race, but think of this 1st. You frequently see other races in books who all act and feel like they are human. So rather than creating a new or rarly used race you could take a frequently used race and try to put a more alien feeling to them. Make them seem like a different and unique race rather than just a different colored human. This is probably more diffucult than it sounds, but theres something to think on.
