Rock Hard is the second book in The Sinners on Tour series by Olivia Cunning. Two years ago, Sed gave Jessica an ultimatum, and she left him heartbroken. Since then, Sed has been trying to forget her, but to no avail. When he sees her working in a strip club, his jealous rage is ignited; Jessica has always belonged to him.

Heartbroken herself, Jessica had made her choice and ended their engagement. She's tried to forget Sed by avoiding men entirely, yet she can't shake off her hatred for him and his insatiable sexual appetite. When they both find themselves trapped on the Sinners' tour bus for the summer, their fiery passion rekindles, reminding them of the countless reasons they never should have parted.

Their time together brings back memories and the undeniable chemistry that still exists between them, leading to a rediscovery of their unique penchant for public encounters. However, this comes with the risk of not only mutual heartbreak but also the danger of scandalous public exposure.
