I don't like it at all. It's trendy, trashy, lightweight, and dated (or will be, in 50 years).
That said, if you
must use it, spell it
Nevaeh. As much as I hate
Nevaeh, I absolutely
despise Neveah and other such "spellings", because
Nevaeh's supposed to be "
Heaven" backwards, and Neveah (for example) defeats that whole purpose by spelling "
Heaven" "Haeven". And that's just illiterate and stupid to me.
