Query: The 'Club' makes a comeback!

After a couple of less-than spectacular entries in this series, 'The 5th Horseman' marks a return to the more suspenseful tone of the earlier books. The plot, with its possible connection between big-city hospital corruption and a series of apparent mercy killings, will definitely keep readers guessing!The ladies of the 'club' have a few more personal conflicts than usual, which adds a few wrinkles to their friendship, and breathes a bit of fresh air into the usual characterizations. Each one has a significant role to play, in contrast to the last two books which focused more on Lindsay.This is a good jumping-on point for those who are new to the series.
