I love the sound of all of those. I should read Red Herring. I remember reading the summary and thinking it was interesting, especially cause it has House stuff in it right? I should definitely get on that, and I'll let you know what I think.
Left and Leaving would be absolutely amazing. You already know my thoughts on that. I adored it!
And a sequel to In Pieces? Course I'd read it!
So hey, do what you think would be most fun
