First up, this is a stand alone with a HEA. It is a part of a series but they can be read in any order which is a plus.

This story starts long in the past when 16 year old Heidi asks her brother's mate Titus (friend to those who don't understand UK English) for a kiss. Titus has no clue that he is Heidi's first kiss. Time passes on and life has happened. Heidi has moved away from En Zed and gone away to England. She has her reasons for this but she is happy as a teacher to young children in a small village in England. Until one night when she gets a phone call from a person she never really expected to hear from again.

Titus is in England hoping to secure some funding for medical research his company in En Zed was close to having a break though in. The research would help women who struggled to get pregnant. But there is a catch, Titus doesn't want to go on his own so he decides to reach out and invite Heidi. The pair meet up in England and meet the billionaire who seems to think they are a couple. And that the donor wants Titus to come and live in England for two years to complete the research.

Apparently there is a spark that still lingers from that long ago kiss and Titus and Heidi start to explore their feelings and realize that they have fallen in love.
