Are Houri immune to Blinding Beauty of a Nymph?

[Nyx1607]

Since Houri are half Nymph and live with their Nymph mother for at least part of their life, I thought that they'd be immune. However I can't find anything that says so, thus I'm assuming they are not immune. Does anyone know the answer?

It is a 3rd party product, so you will not find a definitive answer in the Paizo forum.
That said, looking at the rules, the Houri are humanoid and so susceptible to Blinding beauty, but the nymph can suppress the ability as a free action, so she need only to be extra careful and keep it suppressed for most of the time.
