Pride and Pyramids by Amanda Grange and Jacqueline Webb (2012)

Pride and Pyramids
How can you not love a Pride and Prejudice retelling which is essentially P&P combined with The Mummy

Pride and Pyramids finds Elizabeth and Darcy married with five (six?) children and in search of a bit of adventure.  Their cousin proposes a family trip to Egypt to join him on an expedition to Egypt to find an abandoned tomb. There's also a story about a restless Egyptian spirit and a little mystical element. 

Nice depiction of well-loved characters, a setting that is original, and lots of good characters. Quite fun!
