Geologist here: no. Geomagnetic field reversed thousands of times in the Phanerozoic (last 650 My) without any relation with mass extinction events. Organisms can deal with this kind of events.
"The Ends of the World" is probably the best one. "The Rise and Fall of the Dinosaurs" is also a good one, and it doesn't focus purely on the dinosaurs as the title suggests, but about how we know how they evolved and existed.

It doesn’t look like magnetic pole reversals cause mass extinctions.
So we'll hopefully have hundreds of years, if not thousands of years to prepare.

If things truly get bad, we are not entirely out of options (though powering the aforementioned shield might be somewhat difficult).
