I have currently almost finished “The Forge of God” by Greg Bear.
It is a “Earth is threatened by a cosmic plague” type of story with strong science background and some truly alien alien encounters and leaves you in the dark about what the heck is actually going on for a long time.
But it is much more serious and lacks the light-heartedness of Hail Mary.
Depends on what parts you liked most.

Can recommend it nonetheless.
In case you’re unaware, there’s a sequel called The Anvil of Stars. It has a somewhat different feel than the first, but also a really good book.
Noted, and put on my book bucket list! :-)
