I reckon that's the last we've seen of Ollie Axford,' I said.
'I wouldn't be so sure TJ,' said Nesta. 'I bet he calls and asks you out.'
'Nah. He looks like a player,' I said. 'You know the type. Too much of a twinkle in his eye to be trusted.'
'A bit like Luke then,' said Lucy.
Boys are like buses for TJ. No sign of one for ages and then two come along at the same time! First there's charmer, Ollie Axford, and just when TJ has decided that he could be the one, old flame, Luke De Biasi tells her that he wants to re-kindle their romance.
TJ is torn between the two boys, and unhappy that events have conspired to make her appear to be a two-timer. But all of this seems unimportant when someone close to her is taken seriously ill.
More than ever, TJ needs a clear head and the support of her friends - Lucy, Nesta and Izzie!
