"In the close-knit town of Sullivan's Crossing," Wait, I'm confused! Is this a cosy mystery about a bunch of knitting club "sleuths"? Never mind! "...four siblings gather for a family wedding - and find their bonds tested as" the Sullivans cross each other repeatedly, angering everyone until the entire town becomes embroiled in an almighty gun-battle leaving the whole population dead. Now that would be a cosy mystery! As for this? Meh.
