GREP quotation mark marks across line breaks

I'm trying to GREP the whole of something similar to the following. There are paragraph returns at the end of each line. Regardless of my/your/our thoughts on the structure, I'd like to find a GREP that can capture the lot, including the quotes.

"Lorem ipsum dolor sit amet.

Aenean a finibus odio.

Vivamus vitae eleifend quam, vel faucibus quam.

Donec mollis ut arcu a pretium.

Suspendisse vitae egestas erat."

The paragraph returns are breaking my attempts however. I'm not after something that I'll hit "Replace all" on, I'm happy to supervise it. So not to worry too much about false positives.
