Anyone remember this book?

[noradelphine]

So I really don't remember a lot just that it really stuck with me

Lilac cover - in hardback

Think it would of been released sometime between 2008-2012

About time travelling or alternate universe

Sorry that it's so vague. Complete long shot. But does anyone know the book?

Hi there. Did some googling. Is it the case of Seargant Grischa by Arnold Zweig?

What sort of age group was it aimed at? Kid's picture book, chapter book for e.g. 10YOs, young adult?

Think the PP's suggestion is a bit off - that's a German book published in 1927 about a Russian soldier in WWI!

Pre teen I would say....

When You Reach Me by Rebecca Stead? It has a time travel theme, published 2009. Doesn’t seem to have a lilac cover though.

Thanks for the suggestion... but it's not the one
