A SWEET AND LOVELY JOURNEY
Format: Kindle
These characters were so much fun. The story flowed beautifully with a strong love and a sweet little boy, who sometimes was a holy terror. My only child was a boy and I could relate to adding another “mom” to our family. That little boy is now, himself, a grandfather (Poppy) to three sweet kids.

Heartwarming and adorable
Format: Kindle
It's not often that I cry happy tears but damnit this book made me well up at the end. I adored every single word of this story. It was just adorable and both women are so so sweet and while it wasn't angst free none of the angst came from miscommunication or anything cliche. This was just a great time from start to finish. I lost sleep to read and I have no regrets.

A Captivating Romance of Love, Growth, and Second Chances
Format: Kindle
Erin Corcoran, a single mom still reeling from her divorce, hires a babysitter for the summer, never expecting to fall for her. Blair Breckenridge, fresh out of college and unsure of her future, takes the job to appease her parents but quickly finds herself drawn to Erin and her son. As their connection deepens, Erin fears Blair’s impulsive nature, while Blair must prove she’s ready for the responsibilities of love and family.
Fallen Together by Erica Lee is a beautifully crafted romance that balances emotional depth with an engaging storyline. The novel delivers well-developed characters who experience genuine growth, making for an authentic and compelling read.
Erin is a woman scarred by abandonment, hesitant to trust again, while Blair, despite her initial uncertainty about life, displays remarkable maturity in the way she cares for both Erin and her son, Nolan. Their dynamic is both tender and complex, as Blair proves she is more than just a carefree young woman, she is someone capable of deep love and responsibility. Nolan himself is a delightful mix of chaos and charm, adding a layer of realism and heart to the story.
The novel’s strength lies in its character development and pacing. Both protagonists evolve naturally, making choices that feel true to who they are while ultimately prioritizing what matters most to them. The chemistry between Erin and Blair is undeniable, and their journey is filled with emotional nuance, humor, and warmth.
With excellent plot development and a steady narrative flow, Fallen Together is a captivating read that holds engagement from start to finish. Erica Lee has crafted a romance that is not only passionate but also deeply satisfying in its exploration of trust, love, and the courage to embrace the unexpected.

A delightfully wholesome romance
Format: Kindle
This book is the perfect example of why I love Erica Lee's writing so much. She has an amazing talent for depicting love and relationships in such a wholesome and compassionate light, and it makes her books a delight to read and this is no exception. It doesn't hurt that she manages to balance humor, spice, and snark in a way that has me consistently falling in love with her characters.
I seriously can't recommend this book enough. I had to force myself to put it down at 1 AM and the lost sleep was absolutely worth it.
