As of August 2018, the series is composed of 9 novels and 53 short pieces (short stories and novellas, with most collected in 3 anthologies), all of which fit into a fictional timeline stretching from the Big Bang's singularity of the past to the eventual heat death of the universe and "Timelike Infinity"s singularity of the future. An omnibus edition of the first four Xeelee novels ("Raft", "Timelike Infinity", "Flux", and "Ring"), entitled "Xeelee: An Omnibus", was released in January 2010. In August 2016, the entire series of all novels and stories (up to that date) was released as one volume in e-book format entitled "Xeelee Sequence: The Complete Series". Baxter's "Destiny's Children" series is part of the Xeelee Sequence.
