Simon Stephens' latest show was born out of a workshop with young people and features a hugely impressive teenage cast from across west London.

They may have struggled to make it to rehearsals on time, according to director Sean Holmes, but they had no problem holding the attention of a packed house. 

Checking in at just over an hour, Morning explores some of the issues affecting youngsters - namely disaffection with seemingly everything. 

It opens with Stephanie saying a painful goodbye to best friend Cat, who is about to leave for university. 

Left with just her younger brother Alex and slightly soppy boyfriend Stephen, plus the looming presence in a cocoon-like tented room, she appears strangely disconnected. 

This anaesthetised existence leads to a desperate search for thrills, or feeling of any kind, and ultimately the shocking act of violence at the heart of the play. 

The young cast are uniformly good but Scarlet Billham is particularly impressive as Stephanie, imbuing her with an edgy energy. 

Morning captures the disorientating twighlight world between youth and adulthood but is also wildly funny in places. 

There are many similarities with Skins but this is much braver stuff and while Channel 4's controversial youngsters are happy to get their thrills from booze and pills, the Lyric's seek theirs from much darker sources. 

A more fitting comparison would perhaps be recent Lyric hit Three Kingdoms, which shared a sense of the absurd and created a similarly unsettling but strangely beautiful world. 

Either way, this is seriously grown-up stuff from a young cast of whom we can surely expect to see plenty more.
