The Shy Guy by Nicola Marsh

I’m outgoing. He’s shy. We’re opposites in every way. Now I’m stuck with him for two weeks. This should be fun…
Reclusive children’s author Bo Bradford is on a tight deadline and the last thing he needs is a new illustrator barging into his orderly world and turning it upside down. Being the number one bestselling author means everything to him and no way will he let some bubbly, sassy illustrator disrupt it, no matter how badly he wants her.
Tahnee Lewis falls for Wally the Wombat like the rest of Australia, but when she lands the dream job of illustrating Bo’s incredible books she doesn’t expect to find him as recalcitrant as his creations. She has two weeks to make the most of this once in a lifetime opportunity and if she can have a little fun along the way with the hot writer, so be it.
But when she finds herself falling for the hermit, will she be able to walk away?
