Feather
M. G. Leonard
Walker Books

This is the fourth and final book in what has been an absolutely brilliant series, a series that celebrates friendship, bird watching and the natural world. Herein the Twitchers find themselves
on the trail of a gang of ruthless rare artefact thieves as well as protecting somebody who may have been involved in the crime.

The story begins when Ava is on an end of term class visit to the Swan natural history museum. An alarm sounds and hearing a rustling, she delays leaving and by chance is present when, what turns out to be a daring and well-executed robbery of rare, vintage bird ‘skins’ takes place. Who would want such things – a fashion designer perhaps?

Once outside the museum she encounters an unusual girl with a pet raven waiting at the bus stop opposite. Does she know anything, Ava wonders. With the school trip suddenly curtailed, and a possible clue in her bag, rather than going back home early, she messages her friends and she decides to head off to Briddvale and seek the help of the other Twitchers. Needless to say, the Twitchers are immediately onto this, especially as it involves rare avian specimens of historical importance.

Ava takes the lead in this adventure and some of her actions are exceedingly risky, especially as she is soon as anxious to help Rae (the bus stop girl), who is clearly in need, as she is to get to the bottom of the feather heist, though the two strands are intertwined.

M. G. Leonard includes an amazing amount of detail about bird species and the history of scientists such as Wallace and Darwin; and she clearly respects her audience showing rather than telling lots of the story. Inspired by a true crime, this tension-filled mystery is a superb conclusion to the seasonal quartet and perfect for deep thinking nature-loving readers.
