Suggested Listenng/Reading Order?

I'm listening/reading to Backyard Starship for the first time and started with Backyard Starship Book 1 and have gotten part way through Book 19, I haven't read any of the other companion series yet but I'm hoping that some of the dangling questions in my head are actually answered in there, like the whole combidrive thing and where it came from and its possible connction to the peacemaker war, I'm guessing is all in the the peacemaker war series?

However I'm not sure what is the best order to read them in to avoid giving myself spoilers and knowing the answeres to mysteries before reading the book telling me what the mystery is?!? I had thought publication order possibly but the publication order differ for physical and audiobooks obviously and some of the suggested orders I have found are years old and contradict both publication orders?

Have the authors ever given a suggested reading order or something similar?

Finding myself totally lost and annoyed that some threads aren't answered and the books just blow past them. Can someone help or am I cursed to continue like this and having to read/listen to them all with questions unaswered until I find the time to finish one series and then go listen/read the others?
