I listened to the entire series in one collection, and would recommend it to anyone who loves dystopian young adult. While there is romance with multiple characters, this is not BDB, for example. Blue, the main character throughout the series, is of what I'll call the "lower class." In a society divided by blood-type, she is born into slavery because of hers. Living her substantive growing years in a work camp producing the new system by which currency is valued ("scratch" in the books and "s bricks" the form used to back currency). But she is not just a slave; she believes she is a prophesied savior of the favored race, the only free blood type - B bloods or Vemreaux. Her journey to fit into the role she believes she was born to is detailed, filled with adventure, fraught with danger, and suffers the occasional emotional drama. Highly Recommended!!!
