Thunder by Willow Summers is a fun book. Ms. Summers has delivered a well-written book. I love the characters and their interactions. Kudos to Ms. Summers for the awesome cast of characters. Madison and Colton's story is packed with drama, humor and sizzle. I enjoyed reading Thunder, the humor was perfect. I look forward to reading more from Willow Summers in the future. Thunder is book 1 of the Big D Escort Service Series but can be read as a standalone. This is a complete book, not a cliff-hanger.
