In this paper we study the number of rational points on curves in an ensembleof abelian covers of the projective line: Let $\ell$ be a prime, $q$ a primepower and consider the ensemble $\mathcal{H}_{g,\ell}$ of $\ell$-cyclic coversof $\mathbb{P}^1_{\mathbb{F}_q}$ of genus $g$.  We assume that $q\not\equiv 0,1\mod \ell$. If $2g+2\ell-2\not\equiv0\mod(\ell-1){\rm ord}_\ell(q)$, then $\mathcal{H}_{g,\ell}$ is empty. Otherwise,the number of rational points on a random curve in $\mathcal{H}_{g,\ell}$distributes as $\sum_{i=1}^{q+1} X_i$ as $g\to \infty$, where $X_1,\ldots,X_{q+1}$ are i.i.d.\ random variables taking the values $0$ and $\ell$ withprobabilities $\frac{\ell-1}{\ell}$ and $\frac{1}{\ell}$, respectively. Thenovelty of our result is that it works in the absence of a primitive$\ell$-th-root of unity, the presence of which was crucial in previous studies.
