Alongside dating, she juggles her brother's wedding plans, mediating between divorced parents and supporting her flatmate through heartbreak. All while navigating her increasingly complicated partnership with Rory...

As LEVEL sends her further down a rocky path of failed dates, Penny's faith in her ability to help others find love falters. But what if Penny is wrong about her ability to crack the equation for love? What if, all this time, it's been where she least expected it?
