The trilogy: The 5th Wave, The Infinite Sea and the Last Star is one of the better YA series I've read. The story line of the alien invasion is unique and interesting. Over the three books the characters keep evolving, some get stronger while others get weaker. There is enough plot twists to keep YA's interested and work well with the overall story line. It's also good to read a trilogy that has closure and may not end the way some would like but has a satisfying conclusion.
