Under the Influence by Karina May

Blake Goldfield is ‘the guy who broke Tinder’ while raising funds for his overseas charity. High-flying banker, Louise Lane, isn’t buying his hot, eligible philanthropist act. In fact, it’s dislike at first sight when she encounters Blake working the bar at her office Christmas party.
Both are at a life crossroads: Blake has begrudgingly left his not-for-profit to deal with Goldies, his family’s embattled restaurant; Louise has just split from her perfect-on-paper fiance.
Blake may be in control of the drinks, but Louise has the power to reject the loan necessary to keep Goldies open…
As Blake and Louise watch their lives unravel, their paths seem to be inextricably tangled. Torn between the weight of expectation and her heart’s desire, Louise searches for a fresh perspective in Peru. First stop: Machu Picchu. Final destination: Love?
