V for Victory by Lissa Evans

It's late 1944. Hitler's rockets are slamming down on London with vicious regularity and it's the coldest winter in living memory. 

In a large house next to Hampstead Heath, Vee Sedge is just about scraping by, with a herd of lodgers to feed, and her young charge Noel ( almost fifteen ) to clothe and educate. When she witnesses a road accident and finds herself in court, the repercussions are both unexpectedly marvellous and potentially disastrous - disastrous because Vee is not actually the person she's pretending to be, and neither is Noel.

The end of the war won't just mean peace, but discovery...

With caustic wit and artful storytelling, Lissa Evans elegantly summons a time when the world could finally hope to emerge from the chaos of war.
