From the author of the bestselling The Girl in Steel-Capped Boots and The Girl in the Hard Hat, comes another scintillating romantic comedy, this time set on the beautiful Queensland coast. The perfect summer read! 'We can't choose who we fall in love with. It could be our best friend ... or our worst enemy.' Emily Woods counts cracks for a living. Concrete cracks. So when her long-term boyfriend dumps her, she decides it's time for a change of scenery. Her best friend, Will, suggests joining his construction team in Queensland. Working next door to the Great Barrier Reef seems like just the sort of adventure she needs to reboot her life.until she realises that Will is not the person she thought he was. Charlotte Templeton is frustrated with the lack of respect FIFO workers have for her seaside resort. But picking a fight with their tyrannical project manager, Mark Crawford, seems to lead to more complications than resolutions. The man is too pompous, too rude, and too damned good looking. As both women strive to protect their dreams and achieve their goals, they discover that secrets will come out, loyalty often hurts, and sometimes the perfect man is the wrong one.

I was able to use two of the 35% coupons in the shopping cart for the non-preorder books. Because paying 62¢ is so much better than 95¢

I imagine the 9¢ books are couponable, too. But I didn't think to add any coupons when I bought 8 of them earlier
