13 Reasons Why's season 2 is out now on Netflix - and here's a recap of season one.
13 Reasons Why is based on Jay Asher’s young-adult book by the same name.
The first season focused on Hannah, played by Katherine Langford, who took her own life and left behind a series of 13 cassette tapes for friend Clay (Dylan Minnette).
Ahead of Season 2, Netflix has released a video recap of the first series.
"Why would a dead girl lie?" asks Netflix.
Season 2 will pick up in the aftermath of Hannah's death.
In a first trailer, Clay is seen receiving a series of mysterious polaroids with messages, including one saying: "Hannah wasn't the only one."
13 Reasons Why season 2 will be available on Netflix on May 18 with all episodes available to stream immediately.
In an interview with The Hollywood Reporter, showrunner Brian Yorkey revealed how season 2 will focus on a case of sexual assault as well as gun culture.
It's understood the new episodes will see Jessica Davis (Alisha Boe) coping after being attacked by Bryce Walker (Justin Prentice), while Tyler Down (Devin Druid) will be seen in a storyline involving school shootings.
Yorkey also recently revealed how Season 2 would work following Hannah's death.
"This year will be 13 different narrators. You are the first to hear that," he told DigitalSpy. "Here's what I can say and I don't mean to be a tease, but I also do think, I hope that one of the pleasures of watching the first episode will be asking yourself, how is this going to work without the tapes?
"And whether or not we made it work will be up to every sort of viewer to decide.
"But what we do have that's interesting, I think… the story of Hannah's death and how she died and the way especially her parents pursue justice, and also the way Clay continues to pursue justice for Hannah, that I think provides us a sort of structural idea, that not only provides the engine for 13 episodes, but also the voiceover, which is not cassette tapes, but something different this year."
He teased: "I realise I am being very coy, but I have to be coy."
