"Shadowhunters" returns for the second half of season two on MONDAY, JUNE 5 (8:00 - 9:00 p.m. EDT), with Shadowhunters and Downworlders reeling from what happened at the New York Institute in the winter finale. As the rift between the two sides grows larger, the team and their Downworld friends and lovers are put in the middle of the dangerous divide. Torn between the Clave's rules and what they feel is right, Clary, Jace, Alec and Isabelle struggle to help forge a new beginning. Relationships will be tested, a new Shadowhunter named Sebastian will join the fray and the Seelie Queen will step out of the shadows in the summer season.

In the season three premiere of "Shadowhunters," secrets abound as the Shadowhunters and Downworlders try to get back to normal after Valentine's death. Clary struggles with keeping her secret about Raziel's wish, while Alec pushes Jace to come clean about whatever Jace and Clary are hiding. Luke must use tough love to keep his secret hidden from Ollie who is on the warpath for answers. Magnus hides his true feelings about his new position in the Warlock community from Alec. Meanwhile, Lilith sets a plan in motion in New York City as Simon spends time in the Seelie Court.

Freeform is closing the doors of the New York Institute earlier than expected: Shadowhunters won’t return for a fourth season, TVLine has learned.

The supernatural drama will wrap things up in the spring of 2019 with a 12-episode run — aka Season 3B, titled Shadowhunters: The Final Hunt — that will include a two-hour series finale event.

Season to date, Shadowhunters is averaging barely 400,000 total weekly viewers, down sharply from Season 2 and ranking fifth ranking all current Freeform programs.

“We are very proud of Shadowhunters, a series that broke new ground in the genre world and became a fan favorite,” the network said in a statement. “However, along with our partners at Constantin, we reached the very difficult decision not to renew the show for a fourth season. But as big supporters and fans ourselves, Freeform insisted on and championed the filming of a special two-part finale that would give devoted fans a proper ending.”

Based on the Mortal Instruments novels by Cassandra Clare, Shadowhunters starred Katherine McNamara as Clary Fray, an aspiring artist who learns she’s a human-angel hybrid destined to help protect the New York City streets from all manner of creatures that go bump in the night. The series also starred Dominic Sherwood, Alberto Rosende, Matthew Daddario, Emeraude Toubia, Alisha Wainwright, Isaiah Mustafa and Harry Shum, Jr.

Shadowhunters wrapped the first half of its third season in May with a fiery finale that ended with the team believing Clary to be dead. (For what it’s worth, executive producer Todd Slavkin confirmed to TVLine that McNamara will remain on the show, hinting that “the fact that Jonathan’s hand grabbed her from that coffin means something moving forward.”)
