omega picks up not long after infinity left off, with noah, cade and kori pursuing dylan through parallel universes in order to stop him from killing all the kori's. the problem is the cuff enabling their time travel is acting up, and the reality they end up stuck in is more dangerous than any they've faced before.
to a degree omega is a standalone, because it focuses on noah and his constant, ash, instead of cade and kori who are secondary characters here. but understanding the plot and the action really does require familiarity with the first book, so i would recommend people start there.
as lead characters noah and ash prove to be as compelling as cade and kori were. their connection is just as apparent, and given the reality they've lived in, is almost easier to accept than it was for cade and kori. the big bad here shifts somewhat, because even though dylan is still a threat, this new world they've inhabited has even bigger and badder villians. the omega project the book is titled after has huge implications for ash, in particular, and for all the characters, all of humanity, all possible versions of humanity, more generally.
skipping through alternate worlds continues to add to the adventure, and the book ends with a new threat. i'm certain there will be a third book in this series, possibly more, because i can't imagine things being resolved so easily, and i'm curious to see what set of characters will lead the third. if we'll get new ones or if we'll alternate between the core four characters in the series.
**omega will publish on august 1 2017. i received an advance reader copy courtesy of netgalley/entangled publishing (entangled: teen) in exchange for my honest review.
