It looks like the upcoming Mass Effect: Andromeda will be following its predecessors and expanding its story into the world of books. Titan Books has announced a brand new series of four novels that will release intermittently starting with one called either Mass Effect: Andromeda: Initiative or Initiation, depending on if the Press Release or cover is correct, in August 2016 with the final book releasing in March 2018.
Here's the excerpt from the presser:

Titan Books is currently being scarce with concrete story details on the books, but it won't be too long until we know more. Mass Effect: Andromeda released a new trailer at the EA Play Press Conference during E3 2016, but was admittedly lightweight in revealing much about the game. We hope to hear more about the game this November, around the time of N7 Day.
