The Thousandth Floor is a five-book fiction series by Katharine McGee, published between 2016 and 2018. The list includes both English and Spanish editions, with El Piso Mil and Vertigo appearing alongside the English titles The Thousandth Floor, The Dazzling Heights, and The Towering Sky. The core trilogy follows a clear arc from The Thousandth Floor (2016) through The Dazzling Heights (2017) to The Towering Sky (2018).
For English-language readers, starting with The Thousandth Floor and continuing through The Dazzling Heights and The Towering Sky is the recommended path. The story builds across all three books, so reading them in order matters. The series wrapped up in 2018 with The Towering Sky.
