If you loved watching Etta and Nicholas slip through hidden passages while the Ironwoods closed in and the astrolabe’s paradoxes loomed, you’ll click with the crew of Invictus. Far and his team pull audacious heists on the Titanic and ancient Rome, only to uncover a timeline-destroying mystery that forces them to race through history the way Etta and Nicholas did—hearts on the line, consequences catching up.

Etta’s quest for the astrolabe under Cyrus Ironwood’s threats mirrors Esta’s mission to infiltrate 1902 Manhattan and steal a dangerous magical book from the Order. Like Etta playing by enemy rules while plotting her own moves, Esta embeds with thieves and con artists, outsmarting a powerful cabal as every clue raises the stakes.

If Etta and Nicholas’s chemistry under duress—trading trust and betrayals while dodging the Ironwoods—hooked you, Ruby Red delivers that same spark. Gwyneth discovers her inherited ability to time travel and is thrust into the Guardians’ schemes alongside Gideon, where banter, jealousy, and danger mix as they navigate 18th‑century London intrigues.

Etta’s century-hopping race to keep the astrolabe from rewriting history finds a kindred spirit in Timebound. When Kate learns to use a Chronos medallion, she must stop a timeline-altering plot that echoes the way Etta’s choices ripple through centuries—family legacies, moral gambles, and life-or-death decisions across eras.

If you enjoyed switching between Etta and Nicholas’s viewpoints—seeing each side of their trust tests and sacrifices—These Broken Stars uses dual POV to similar effect. Lilac and Tarver survive a crash on a mysterious planet, and their alternating chapters build tension and intimacy the way Etta and Nicholas’s did under fire.
