There's not long to wait before the second season of 13 Reasons Why, following the success (and controversy) of the first.

In this article we reveal when the second season of 13 Reasons Why begins, how and where to watch it, and what to expect from the new series.

When will Netflix release season 2?

Netflix has announced that the second series of 13 Reasons Why will be released on Friday 18 May. Because it's a Netflix original series, every episode of the new series will appear simultaneously: you won't need to wait a week for each episode.

How to watch 13 Reasons Why

13 Reasons Why is a Netflix original series, and it will initially be available to watch on Netflix and nowhere else. (The first series is now available on Amazon Video and on DVD.)

You can watch online at Netflix.com, or use the apps for iOS, Google and more. You'll need to take out a subscription (the cheapest is £5.99/$7.99 per month) but Netflix offers a free trial for one month and you can cancel at any time.

You can pay extra to enable Netflix streaming on more than one device at a time (you can watch on your laptop, PC, TV, tablet or phone) and to unlock HD and Ultra-HD content.

Log into your Netflix account and use the Search function or look under Netflix Originals for 13 Reasons Why, then tap or click to play.

What to expect from 13 Reasons Why season 2

Some unavoidable spoilers may follow, so those who have not yet seen series 1 may wish to exercise caution.

From what we know so far, it looks like most of the main characters are back: Clay, Hannah, Tony, Bryce, Jessica, Zach and Mrs Baker all appear in the trailer (we think Clay is imagining conversations with Hannah in the present day, how she would view his actions and so on, rather than as a pre-suicide flashback as in the first series), and we think Tyler is there too. We also spotted an appearance from Ryan, and Wikipedia - citing no source - believes he will be upgraded from a recurring to a main character in the second series.

But there is also a new character whose story is central to the plot, and whose name we don't know. Whereas Hannah sent tapes to Clay in the first series, someone new is leaving Polaroid photos for him to find, and the first has a label reading "Hannah wasn't the only one".

Follow accusations of irresponsibility and even glamorising suicide, the production company appears more conscious of ever of its duty to consider young viewers with mental health problems. There is a website for anyone suffering similar issues or considering suicide or self-harm.
