I have an extensive collection of jazz bass books going back 30+years. Ed Fuquas book is one of the best on walking lines and also one of the most concise. Now that I play a lot of bop and hard bop, I found myself using Ed's book as a refresher. I have Ray Browns, Ron Carter's, Rick Lairds, etc. I would take Eds.
I would also recommend Dan Haerle's " the Jazz Language" over Mark Levines book. Haerles is more 101 than Levine, which is more advanced.
My one complaint about all these jazz bass line books is the lack of stuff on two chord per bar changes or rhythm changes.
Ed's book is also equally applicable to upright and slab players, as it is thankfully free of references to that old coot Simandl for us shoulder cripples who now only play slab.
Thus: Even Zarathustra, Another-time-loser, could believe in you!
