#newspaper cipher

[nyxicnymph]

Anybody wanna help my mom and I decipher this?

The newspaper came today and we like to do the ciphers occasionally, but we're really stumped with this one.

The only hint we're given is that D = F

Here's the puzzle:

"ONAV CVNCRV TVS IUMY OSPWFUHT XISUDUMUXR UHSVRRUTVHMV. AV, U AXEV ANHVF OSPWFUHT HXSPIXR OSPCUWUSF." -MXIR UMXYH

Thank you!
