Girls In Tears by Jacqueline Wilson
The girls are back - but they're not very happy! Ellie's glorious romance with Russell is teetering on the rocks. Magda's lost her pet and is desperately upset (though the others didn't even know she had a hamster!). And Nadine is fed up with the other two lecturing her about the dangers of meeting someone from the internet IRL - she thinks the guy she's chatting to online is wonderful . . .
Buckets of tears are wept and hundreds of tissues are sniffled into - can the girls survive these testing times?
