What are some urban romance novels that involve complex relationship dynamics like love triangles and revenge?

For urban romance novels featuring intricate relationship dynamics such as love triangles and revenge, "One Rocky Term" appears to be a very suitable recommendation. The description explicitly mentions a scenario where a new friendship leads to a rekindled romantic past between the protagonist's boyfriend and her best friend. This sets up a clear love triangle with inherent conflict and emotional depth. The tag 'revenge' further suggests that the characters might not just be navigating their feelings but also acting upon past grievances or trying to right perceived wrongs, adding another layer of complexity to the narrative. The 'billionaire' tag also hints at potential social and economic dynamics that could influence the relationships.

This novel seems to delve into the messy, often painful, but compelling territory of interpersonal relationships where loyalty, love, and past affections collide. The urban setting provides a contemporary backdrop for these dramatic events, making the struggles relatable to a modern audience. The interplay between friendship, romantic history, and current romantic interests, coupled with the potential for revenge, makes "One Rocky Term" a prime example of the kind of novel you're looking for.
