Does she survive the book's version of The Red Wedding?
She doesn't exist in the books. In the books Robb married Jeyne Westerling a daughter of one Lord Westerling one of the Lannister bannermen. When Robb's forces took the Westerling's keep Robb was wounded and she nursed his wound...He found out his brothers were killed by Theon and they slept together which is pretty much what happened in the TV series.
In the books she never accompanies Robb to the "Red Wedding" and remained with her family. There is no pregnancy in the books as well, although fans continue to speculate that she secretly carries Robb's heir even though there's not any evidence.
In fact I would say the fact that Talisa (Jeyne's replacement for the show) has died with any possible heir to Robb dying with her that means it's unlikely any book storyline involving an heir of Robb Stark by his Queen will occur.
