3.3 3.3 out of 5 stars 3 ratings

TWO BOOKS IN ONE. FREE IN KINDLE UNLIMITED.

Professor Valentine:

Diego Valentine is gorgeous. Infamous among the psychology department, Cassie knows of his dashing looks and charming demeanour. But she doesn’t predict her secret yearning for their private weekly tutorials in the confines of his office.

Overtime, their friendship blooms into something more, and the two can’t ignore their fiery chemistry.
But he is almost twice her age and going through a divorce.

It is so wrong yet feels so right.

Can they act on their feelings or push them aside?

Forever Valentine:

Being in a relationship with your ex-university professor isn’t taken that well by everyone around you. But Cassie doesn’t regret a moment of time spent with Diego Valentine, her first and only love.

Still, it isn’t all sunshine-and-roses. He is almost twice her age and dealing with a drug-addled ex-wife. Meanwhile, she is trying to complete a psychology degree and enjoy an ordinary university experience.

Will they overcome these challenges or break apart from the pressure?

Enjoy these two steamy stories compiled together in one book.

Full content visible, double tap to read brief content.

Diana Vale is a British contemporary romance author. She writes grounded, coming-of-age new adult stories with warm heart and plenty of steam. Her characters can be described as confident nice guys with a light-hearted sense of humour, and spunky imperfect girls with sass and fire.

Her Kirk Uni-Verse consists of three main series: the Kirk University series (heterosexual couples), the Kirk Guys series (m/m couples), and the Kirk Gals series (f/f couples). All books take place at the charming fictitious city of Kirk in northern England (based on the real-life University of York).

Follow these students as they enter adulthood on their quests for personal growth. Watch as they find their soulmates along the way. Various topics are explored, from addiction and OCD, to the struggles of falling for your significantly older university professor. But inevitably, love prevails.

If you enjoy sexy, diverse, and thought-provoking tales, dive on in today. All books are exclusively in Kindle Unlimited.
