A tie-in novel for Arrow has been announced, connecting the events of the show's season 5 finale to the season 6 premiere episode. As superhero TV series are inclined to do, Arrow ended last season on a bang. In this case, it was a literal one, as explosions went off all over Lian Yu. For now, it's unclear who survived the event, though most of Team Arrow have already been confirmed to be back. Although the first episode of season 6 will focus heavily on the fallout of the season 5 finale, part of the story will remain untold.

Since its early days, Arrow has used canon stories in both comics and books to flesh out the gaps between seasons. The Flash has followed suit, offering a number of interesting tidbits for completist fans with its supplementary material. Though such Arrowverse comic books and, to a greater extent, the books haven't been largely publicized in the past, that's not the case this time around.

Arrow co-creator and executive producer Marc Guggenheim took to Twitter to announce the arrival of the new Arrow tie-in novel coming in 2018 (see the post below). Titled Fatal Legacies, the book will see writer James R. Tuck giving life to a story that was written by Guggenheim and picks up following the events of the season 5 finale.

Along with the announcement by Guggenheim, the Amazon listing for the book has a brief synopsis for what the story will be about:

The untold story bridging between ARROW seasons 5 and 6, exclusive to this novel! In the devastating aftermath of season five, Team Arrow must resume their mission to protect Star City. Those who have survived Chase’s trap on Lian Yu discover that his plans did not end there. If his legacies aren’t stopped, countless more will die. Co-authored by Arrow series producer Marc Guggenheim and James R. Tuck (Robin Hood: Mark of the Black Arrow).

Like previous ancillary media, the book won't be required reading. Still, it sounds like Fatal Legacies will explore that backup plans that Prometheus had made, prior to the events of the Arrow season 5 finale. There's also no word whether or not the show itself will reference anything that happens in Fatal Legacies - something that may or may not happen, seeing as the book will go on sale around the time that Arrow season 6 is halfway done.

Regardless, Arrow season 6 will have plenty to deal with in the present. Black Siren will be back and causing trouble for Oliver and Dinah. Meanwhile, Oliver's former ally Anatoly will be a full-on antagonist this season. Given the blind spots Green Arrow has for both of these enemies, Team Arrow could be in a lot of trouble in the episodes to come.
