The Golden Day by Ursula Dubosarsky is an easy to read YA novella set in a Sydney girls's school in 1960s.
Eleven girls and their teacher Miss Renshaw take an unplanned excursion outside the school grounds one sunny day, and their teacher strangely disappears.
With an eerie feeling like that in Picnic at Hanging Rock by Joan Lindsay, The Golden Day is eerie in a subtle way, although Australian author Dubosarsky doesn't attain the giddy heights of Joan Lindsay in her execution.
This novella is well-written with a mystery to excite YA readers and is suitable for middle grade readers too.
My rating = ***
P.S. I won this copy of The Golden Day by Ursula Dubosarsky in the Australia Day blog hop in 2015, thanks to Allen & Unwin.
