I've read the flood and half way finished with the fall of reach. And as a adult this is my first book series I've read for fun. And I must say......I've really enjoyed the time I've spent reading this series. I love laying down for the night and reading Halo much better then reading from my phone. And much better the simply watching TV. After the fall of reach I plan on reading silent storm and from there......I kinda want to read one based more on the convent and their way of life
