How to Choose
Read The Bride Test and The Heart Principle first to finish Hoang's series, which grows more emotional with each book. Talia Hibbert's Brown Sisters trilogy is the best next stop, and Act Your Age, Eve Brown has an autistic hero who should interest fans of Stella. For a similar smart heroine, try The Love Hypothesis or The Soulmate Equation. If you want a gentler story without much spice, The Rosie Project and Eleanor Oliphant Is Completely Fine share the same interest in people who think differently. Note that Hoang's books are quite explicit, while others on this list vary in heat, so check the reviews first if that matters to you.
