Description
The Third Day, The Frost
Ellie
 and her friends, an unarmed bunch of amateur teen fighters, have 
achieved more than they ever thought possible. But it’s not enough. The 
war wages on, their families are in captivity and their country is on 
its knees. Hiding back in Hell, the friends face a big question: what to
 do next? The gang has another success when they manage to rescue Kevin.
 He returns to them equipped with a new knowledge of explosives. 
Suddenly the question of what to do next becomes clear – launch an 
attack on the major enemy target of Cobblers’ Bay. 
Can
 Ellie, Homer, Fi, Robin, Lee and Kevin really stage a major military 
attack on the enemy? And in their attempt to pull it off, what will they
 have to sacrifice? They have already lost Corrie and Chris; who else 
will the group have to lose in their desperation to defend their 
country? The Third Day, The Frost, draws the reader deeper into the 
struggle of these ordinary teens attempting to survive in extraordinary 
times. It is a tense and moving read that will stay with you forever.
The Dead of the Night
When
 their country is invaded and their families are taken, eight high 
school teenagers band together to fight. Seventeen-year-old Ellie and 
her friends have survived the invasion, but two of their bands are 
captured: Kevin is imprisoned and Corrie is alive, but in a coma. Homer 
and Ellie are determined to get them back and to continue their campaign
 against the enemy. They discover that there are other rebels out there,
 fighting the invaders – but who are they and can they be trusted? As 
the pressure grows, can Ellie work out her conflicted feelings for the 
brilliant, arrogant Homer and the strong, gentle Lee? As war rages, and 
the enemy closes in, Ellie and her friends must once again fight for 
their lives… but how many of their band will be left? A truly involving 
story about teenagers facing the incredible challenges of warfare, amid 
the intensity of first love. Would you sacrifice everything to save your
 country and your family?
Tomorrow When the War Began
When
 their country is invaded and their families are taken, eight high 
school teenagers band together to fight. Seventeen-year-old Ellie Linton
 wants one final adventure with her friends before the school holidays 
are over. Packed in Ellie’s parents’ land rover they drive to the 
famously isolated rock pool Eden dubbed ‘Hell’ by the locals. Returning 
to their home town of Wirrawee, the seven teenagers realize that 
something is seriously wrong. Power to the houses has been cut, pets and
 livestock have been left dead or dying, and most alarmingly of all, 
everyone’s family has vanished. When the hostile armed forces discover 
that the teenagers are lying low in the vicinity, Ellie and her friends 
must band together to escape, outwit and strike back against the 
mysterious enemy that has seized control of their town and imprisoned 
their friends and loved ones…
