This is the third book in this series and it just gets better. This time Kat and the gang are on yacht with a killer. But it seems only Kat can see something wrong. This book kept me on the edge of my seat. I am yelling at Kat don’t go in that cave. But does Kat listen? No. I was also yelling at the others that they should listen to Kat’s instinct about their host. This is a great series and it will keep you entertained and you may get frustrated with Kat when she decides to do crazy things or when the others do not see what Kat sees and do not listen to her. I can’t wait till the next book. The narrator does as great job bringing each character to life. The author has created fantastic characters. I was gifted this book at my request for an honest review.
